This appears to be breaking dsync at the moment and is caused by something committed in the last week or so. This is with the current -git of dovecot-2.2 (eaf276b33). The crash happens all the time - the logs are full of this message.

Hi, Just to confirm this is still a major problem for me with the 2.2.33.1 release (did not exist in previous releases). Reuben On 8/10/2017 6:30 AM, Aki Tuomi wrote: > Thanks!

When in the process of testing out the 2.3.0 version of Dovecot, we noticed that on a busy server, imap-login can sometimes take 100% CPU and remain there indefinitely. We grabbed a gdb trace while it was happening: dovenull 36053 31.2 0.0 60460 17316 ? R 04:38 11:55 dovecot/imap-login root at server [~]# strace -p 36053 Process 36053 attached ^CProcess 36053 detached root at server
