Process Tracing =============== If a Dovecot's process hangs or is just really slow, the best way to debug it is to see what it's really doing. Typically you'd be looking into imap or pop3 processes. Linux ----- ---%<------------------------------------------------------------------------- strace -tt -o log -p <process pid> ---%<------------------------------------------------------------------------- BSDs, OS X ---------- ---%<------------------------------------------------------------------------- # enable process tracing ktrace -f log -p <process pid> # do whatever makes it break, then stop the process tracing: ktrace -C # and see what it's done: kdump -T -f log ---%<------------------------------------------------------------------------- Solaris ------- ---%<------------------------------------------------------------------------- truss -d -o log -p <process pid> ---%<------------------------------------------------------------------------- (This file was created from the wiki on 2007-06-15 04:42)
