Roundcube 0.5.9 really slow suddenly

[NickMDal]

I didn't see a 0.5.9 prefix so used 0.6.

We are about to launch a large website and had RC configured to handle all of the email.  All is on hold until this is resolved.  Any troubleshooting help would really be appreciated.

Debian squeeze was just updated to 6.0.3.  The mail server is fine, the mysql server is fine (used for authentication), the dns is fine, the apache and php setup are fine as well. Roundcube just stalls for no apparent reason after getting the credentials from mysql and before even trying to login to the mail server

Please check your RC version - there is no such thing as 0.5.9, the last in the 0.5 branch was 0.5.4.

What do the RC logs say?

Just told by the server admin that we have 0.5.1.  He will post the logs today.  Thanks for your help.
