Looks like it could be in an infinite loop. To find out where: 1) strace for a few seconds: strace -tt -p 25934 2>log 2) get gdb backtrace a couple of times (2-5 should be enough, preferably slightly different ones): gdb /usr/local/bin/doveadm 25934 bt full <copy&paste the output to mail> cont <ctrl-c> bt full <copy&paste the output to mail> cont <ctrl-c> ..etc..
