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.
