Hi everyone. I'm running Cyrus on my server and so far is running fine... until now that is. I noticed that it took longer and longer every time to reload the imap server. I found this in a mail archive somewhere and it seemed to work:

Take a look at your top output, and see if any IO or CPU activity is
happening. If not, take a truss (Solaris) or strace (?) (Linux) of the
ctl_cyrusdb process. Something that has been plagueing me is that
ctl_cyrusdb runs out of filedescriptor because it opens the same file
about 250 times. So if your truss output shows poll(), and EMFILE, that
might be your problem.
If, and only if that is the case, you might be helped by removing the
deliver-db, the tls_sessions db and all the snapshots. However, make
sure you make backups first! I haven't yet had this problem again on
2.1.16, but I did the first time I started 2.1.16 using my 'old' databases.
Does anyone else experience the 'out of file descriptors (EMFILE)' problem?

My problem is that I don't want to delete all those files every time since they cause loadsa errors while loading cyrus....
This is the actual problem:

Now my question is, what is cyrus trying to do here and how do i fix it?? |
