Apparently it crashed. Getting a backtrace would help. Do you see a core
file in /var/run/dovecot? If not, make sure you have "ulimit -c
unlimited" before starting dovecot. Or I guess you could also run gdb
directly:

gdb dovecot
run -F
<wait for crash>
bt full

Although the pop3-login processes should have gone away if the dovecot
master process had died.
