Here’s a more complex fix that reuses the HTTP connections for the same hosts: http://hg.dovecot.org/dovecot-2.2/rev/26355654c314 On 3.10.2013, at 19.27, Richard Platel wrote:

Did some more digging.

The problem is that the fts-solr plugin has a global solr_conn pointer, that persists between users. I think this patch fixes the problem:

I've confirmed that this problem still exists in 2.2.5

It seems that indexer-worker only init's plugins at startup, so the fts_solr plugin is holding the url= parameter from the first user.

The problem doesn't happen if the indexer-worker process is idle-killed between users. A new process starts up with the new user's userdb settings.

I thought I could work around this problem by adjusting indexer-worker's settings:

service indexer-worker { service_count = 1 idle_kill = 1 }

but these changes don't seem to have any effect, the indexer-worker process still hangs around idling after indexing a user, and isn't idle-killed for upwards of a minute.

Any help?

Hello. We're setting up fts solr and want to have the solr server host be set per-user via UserDB.

It looks like if a user connects and fts indexes mail, and then another user connects and indexes mail, indexer-worker is connecting to the first user's fts host:

User1, hammer@rp-auth-test.com connects, does a SEARCH for the first time, indexer-worker gets UserDB settings and correctly indexes mail on ftsvs01:
