IMP hangs

[Administrador]

Hi, folks. I'm writing because a few of my users are getting this =
message when logging into their IMP accounts:


Fatal error: Maximum execution time of 30 seconds exceeded in =
/var/www/html/horde/imp/lib/imp.lib on line 405

And the syslog says:

IMAP toolkit crash: Lock when already locked

How do I find the lockfiles for each user? where are them stored?
Any comments, please let me know

Luis.
