This happened from one user near noon on the 17th and 19th (today) of
this month. From the backtrace it looks like they were searching, but I
won't know for sure unless I need to ask them. Is this possibly fixed
already? I just haven't upgraded dovecot in a while due to lack of
problems. The sig11 happened a few dozen times, a few seconds apart
each day. I have one coredump from each day, and the size was the
same. This is a trace from only one. The other backtrace looks pretty
much the same.
