[RCU] IMAP Search Timeouts

Good Day Everyone,

I'm having an interesting problem with large mailboxes, searches, and roundcube errors. It seems that any time a IMAP search takes more than a minute to return results Roundcube returns a "Connection to storage server failed." error. If you re-run the search after the error you do end up getting the results without issue.

Here are the details:

• Roundcube 0.8.2
• CentOS 6.3
• php-5.3.18-1.el6.remi.x86_64
• mysql-5.5.28-1.el6.remi.x86_64
• Courier IMAP 4.2.0
• up-imapproxy-1.2.7-2.el6.x86_64
• memcached-1.4.4-3.el6.x86_64

The problem occurs with or without imapproxy and memcache in place.

I figured I'd toss it out here before I go the route of filing a bug report.

Thanks, Ben
