If there were no error messages logged with 1.1.5, there's nothing I
can think of that could explain it.Im not sure when this started, but im seeing very high CPU use in dovecot. I recently swapped our systems to Linux from FreeBSD, and ive also moved versions up a few (now on 1.1.6).
Here's an idea of what im seeing:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
28554 xxx 20 0 11108 1452 1136 R 17 0.0 0:00.76 imap
28542 xxx 20 0 11004 1456 1120 R 16 0.0 0:00.86 imap
Checking what the processes do would be helpful. Both strace (strace -p pid) and a couple of gdb backtraces (gdb -p pid, bt).
