[Dovecot] Dovecot 2.1.7 crash (with core dumped)
Hi,
I'm running dovecot 2.1.7 with vpopmail auth and Maildir on NFS (I have only one POP/IMAP server). All works fine but sometimes dovecot "imap" process crush and I would like to understand why:
Error in log files:

Hi,
I'm running dovecot 2.1.7
you may upgrade to 2.1.17, then try again
there where bugs solved
http://hg.dovecot.org/dovecot-2.1/log?rev=vpopmail
search list for patches
and/or wait for Timo to answer
with vpopmail auth and Maildir on NFS (I have
only one POP/IMAP server). All works fine but sometimes dovecot "imap" process crush and I would like to understand why:

yes i see, sorry i missed it, but looking at your backtrace i dont wanna speculate
however why are using nfs for only one server ?, and why have you set maildir_very_dirty_syncs
also please reread

I'm using NFS for HA and future scalability, I have two pop/imap/mx servers in Active/Passive configuration.
I set maildir_very_dirty_syncs for "Optimizazion" since only Dovecot accesses cur/ directory (for POP/IMAP/Delivery).
also please reread
Yes I know ... in the next months I hope to switch to director. Thanks

I was using DRBD, on these servers, a year ago. But the data store was full and for better future scalability I prefer to switch to an external NAS.

Yes, you're right, but this installation could grow very quickly in the next few months and I have to be ready to add new servers.

i am not convinced nfs is a good choice, but however it should work with right config

so if youre going to grow ,better change to 2.2.x dove versions now
