I have a user with a large mailbox currently containing 19.1GiB with 43144 message count. He has started having an issue where his mail clients will not send or receive.

Great! This seemed to work. I tested this on a cold-standby clone server that I made first, so backups were already covered. I didn’t do this on the Production server yet. In case anyone else needs to do this - I did the following: #Change to Mailcow directory cd /opt/mailcow-dockerized/ #Stop Solr Container safely docker compose stop solr-mailcow #Check Solr Container stopped docker info #Change to Solr data volume directory cd /var/lib/docker/volumes/mailcowdockerized_solr-vol-1/_data/ #Remove empty directory with rmdir and non-empty directories with rm -r rmdir snapshot_metadata rm -r index rm -r tlog if(window.hljsLoader && !document.currentScript.parentNode.hasAttribute('data-s9e-livepreview-onupdate')) { window.hljsLoader.highlightBlocks(document.currentScript.parentNode); } #Change back to Mailcow directory again cd /opt/mailcow-dockerized/ #Restart Solr Container docker compose restart solr-mailcow After a short time the /debug dashboard showed: solr-mailcow (mailcow/solr:1.8.2) (Started on 10/04/2024, 20:21:24) Running . . . if(window.hljsLoader && !document.currentScript.parentNode.hasAttribute('data-s9e-livepreview-onupdate')) { window.hljsLoader.highlightBlocks(document.currentScript.parentNode); } The deleted contents of the /_data/index subdirectory was over 2.7GB. Thanks for all your help @DocFraggle and @esackbauer , much appreciated!

Errors on large Mailbox, logs relate to Solr

I have a user with a large mailbox currently containing 19.1GiB with 43144 message count. He has started having an issue where his mail clients will not send or receive. Checking the Dovecot logs shows me:

On the /debug > System Containers page I can see that Solr shows as:

solr-mailcow
Container stopped or disabled
Stopped

I understood that Solr was deprecated and not required for Mailcow operation. Is that correct, or is it necessary for large mailboxes to act as an indexer?

Additionally, reactivating Solr doesn’t work. I have restarted the container:
docker compose restart solr-mailcow

Which succeeds but Solr is still Stopped. I have changed the setting in docker-compose.yml

- SKIP_SOLR=${SKIP_SOLR:-y}
to
- SKIP_SOLR=${SKIP_SOLR:-n}

But Solr stays stopped. The Dovecot logs are showing the same errors more often, so I would like to fix it before it causes a real problem.

Thanks.

DocFraggle

Please never change the docker-compose.yml directly! Check your mailcow.conf, there you can set the SKIP_SOLR property
Solr consumers a lot of memory and is therefore disabled per default

The problem itself may as well be RAM related… how much RAM do you have?

OSSVirt

Please never change the docker-compose.yml directly! Check your mailcow.conf, there you can set the SKIP_SOLR property

Ah that’s good to know! Thank you. I did check mailcow.conf first and solr was not disabled there.

Yes I think it was RAM related. I did a cold-standby sync onto a VM with 7.75GB RAM and Solr was auto-disabled at that point. It ran previously on a very similar VM. I can’t find anything in the Solr logs that specifically mentions auto-disabling due to RAM, I can post the Solr logs if that helps.

Now I have cold-standby synced onward to a new VM with 16GB (15.25GB available) and Solr will not restart even though there is a lot of free RAM.

But is it likely that Solr is the issue here?

Thanks

DocFraggle

Here’s the part about RAM for Solr during the initial generation of mailcow.conf

mailcow/mailcow-dockerizedblob/master/generate_config.sh#L166

But I agree, 16G should be enough now… there’s really nothing in the logs?

What client is being used by the user?

OSSVirt

Here is the Solr log:

It seems like the same event flow twice, from a quick reading. I rebooted yesterday and today.

The mail client is iOS Mail on an iPhone I believe.

There are plenty of errors in the Solr log but nothing that I can understand as a reason for it failing. But I don’t know Solr at all. I can’t find anything about RAM levels. Maybe I will try to re-index Solr as the docs page explains:

https://docs.mailcow.email/manual-guides/Dovecot/u_e-dovecot-fts/#fts-solr

The real question though, is; Is this issue with Solr not running enough of a problem to potentially be the cause of the outages issue?

Thanks very much for your help.

DocFraggle

OSSVirt I don’t think so, Solr is used for the full text search, i.e. if you search for content inside emails etc

esackbauer

Seems like some of your index files are broken:

OSSVirt Caused by: org.apache.lucene.index.IndexNotFoundException: no segments* file found in LockValidatingDirectoryWrapper

So what the internet says is you stop solr, delete the contents of /var/lib/docker/volumes/mailcowdockerized_solr-vol-1/_data directory (or however your docker volume for solr is named), and start solr again, it should then properly rebuild the index.
Have backup done before you do this 😉

OSSVirt

Great! This seemed to work. I tested this on a cold-standby clone server that I made first, so backups were already covered. I didn’t do this on the Production server yet.

In case anyone else needs to do this - I did the following:

#Change to Mailcow directory
cd /opt/mailcow-dockerized/

#Stop Solr Container safely
docker compose stop solr-mailcow

#Check Solr Container stopped
docker info

#Change to Solr data volume directory
cd /var/lib/docker/volumes/mailcowdockerized_solr-vol-1/_data/

#Remove empty directory with rmdir and non-empty directories with rm -r

rmdir snapshot_metadata
rm -r index
rm -r tlog

#Change back to Mailcow directory again
cd /opt/mailcow-dockerized/

#Restart Solr Container
docker compose restart solr-mailcow

After a short time the /debug dashboard showed:

solr-mailcow (mailcow/solr:1.8.2)
(Started on 10/04/2024, 20:21:24)
Running . . .

The deleted contents of the /_data/index subdirectory was over 2.7GB.

Thanks for all your help @DocFraggle and @esackbauer, much appreciated!

DocFraggle

Great, and was this really related to your user not being able to sync his mail? Is it now working again?

OSSVirt

Well this is the question! 😃

I tested the above fix on a Cold-Standby clone and it seemed to work perfectly. So I will now make the fix on Production and then see what happens.

It may be tricky to know for sure as it was an intermittent issue that appeared only twice so far. If it no longer happens I will declare it fixed, but will maybe never know for sure. Also I guess Solr will disappear from Mailcow in the near future, so that whole issue may go away. If the same thing happens again but without the Solr error in the logs then I’ll know it wasn’t Solr and I’ll keep hunting for the cause.

I’ll definitely come back and add an update onto this thread after I have fixed Production, in case it helps anyone.

It doesn’t look like issue threads get closed on here, so I should be able to add to this discussion next week no problem I guess. 👍️

OSSVirt

Hi again, here’s the update.

I ran the Best Answer fix above on my production server on Saturday 13th April 2024 and everything behaved as expected. Solr runs fine again and there have not been any connection outage issues reported since. It’s too soon to be certain that this fix is the solution to the errors the user was experiencing, but I feel like it probably is the answer.

Now that I’m aware of this situation I am monitoring Solr and watching its memory usage, cache size and document count gradually creep up each day. That would be what I would expect an indexer to do. I guess when it reaches a critical capacity it can’t cope with the scale of the index any further and crashes. Is that right?

Do we know what the critical point is? Is it the JVM memory usage or the index size?

Thanks again for all the help with this before 😃

Same issue and same solution.
