Hi all,

We updated to 1.1.7 a week or two back from 1.1.6 (both standard atrpms builds). Since doing so, twice now I've seen the imap services accept connections but they hang before the banner is printed (pop seems to be unaffected). I see this in the logs:

Dec 23 14:02:15 mail9 dovecot: pipe() failed: Too many open files Dec 23 14:02:15 mail9 dovecot: Temporary failure in creating login processes, slowing down for now Dec 23 14:02:15 mail9 dovecot: Created login processes successfully, unstalling Dec 23 14:02:16 mail9 dovecot: pipe() failed: Too many open files Dec 23 14:02:16 mail9 dovecot: Temporary failure in creating login processes, slowing down for now Dec 23 14:02:16 mail9 dovecot: Created login processes successfully, unstalling

The ulimit for the number of open files on these servers has remained unchanged at 8192 and there are no warnings about too few fd's on dovecot startup. There weren't amazing numbers of imap sessions open at the time (only something like 400-500; we've had 1.5k in the past), so I suspect this is a regression between 1.1.6 and 1.1.7 where you've got a leak of fd's ? If it happens again I'll try and get a snapshot of the fd's open by the master dovecot process.

Thanks,

Mark
