Reading your old mails: are you still using GPFS? This crash just shouldn't be happening, so perhaps something randomly breaks with it. Are you using mmap_disable=yes? Multiple servers can access the same user's mails at the same time?
Yes, we're using GPFS, but haven't turned on mmap_disable=yes. I believe GPFS should handle mmap across the cluster, and it's been working fine without this setting with the old v1.0.0+.
Do you have any idea what the performance impact should be of turning on mmap_disable=yes ?
Anyway Dovecot still shouldn't be crashing no matter what GPFS does, but I won't try to fix v1.0 indexing bugs anymore since I've already done a ton of work to get them more robust in v1.1.
Ok, we are planning to move to v1.1, but figured we needed to first move to a high number v1.0-release to have the option of reverting from a v1.1 if we hit any problems.. Not quite sure how we'll handle this now.
