replication catch up after stop

[Stephen Ingram]

I'm using replication with cyrus-imap on CentOS 5.4 rpm version 2.3.7.
It works very well, but occasionally stops (many times my fault). When
restarting everything, there are log files left in the
/var/lib/imap/sync directory with the name log-# where # is most
likely some process number. Many times if I just leave these alone,
they disappear after a period of time. I'm assuming that they have
processed and that everything is in sync and have verified this to be
the case. Some times, however, they just remain in the directory. I've
looked at the documentation, but it doesn't seem to go into any depth
on this subject. Can someone explain how the log files created in this
directory work and if there is a way to manually process these files?
