Hi there, many thanks for response.
Zimbra IMAP is set to 200 connections at the moment (the default from the GUI).
Is that the same as zimbraImapNumThreads ? (I can't see a way to use zmprov to display zimbraImapNumThreads)
Surely 200 is enough for 10 users - but I'd happily bump it up if necessary.
We are running IMAP proxy.
We've had to restart the server twice today....
I have been noticing errors in the logs about too many files being open.
I had a look at this:
[SOLVED] Mail deferred due to too many files open
This sounded like the solution, but ulimit -n (as Zimbra) shows 524288
Here's some log entries:
