dovecot - Oct 2011 - 1.2.17 Program terminated with signal 11, Segmentation fault.

Hello,

We've had seg faults a couple of times a day on our servers, we upgraded 
to 1.2.17 and still have them.

running a coredump through dbg says:

We use NFS for mail store, and ramdisk for dovecot indexes. We do run 
the mail_log plugin.

Let me know if you need any more info though.
