too many open files problem.

[João Assad]

Hello guys,

cyrus is complaining about too many open files when I try to rename(move 
between servers) or delete a large number of mailboxes.
I have a script that connects to the cyrus master server and issue 
renames or deletes. My script can be configured to close and reopen the 
connection after every X renames/deletes but that doesnt seem to help... 
even if I use 1 different connection for every rename/delete I will get 
the too many open files error after some time.
When moving mailboxes, I get the errors on the backend server Im moving 
the mailboxes from.

cyrus/imap[30082]: IOERROR: creating quota file 
/imap/conf/quota/H/user.658729.NEW: Too many open files
cyrus/imap[30082]: DBERROR: error storing user.658729: cyrusdb error

cyrus/imap[30082]: IOERROR: open on /imap/mboxes/H/user/658729/1.: Too 
many open files

cyrus is started with ulimit -S -n 1000000
