FS#4953 — Switch IMAP/POP3
Scheduled Maintenance Report for Web Cloud
Completed
In order to guarantee the best performances, we prefer to unload the ACE of the SSL management.

We will therefore restart the services IMAP and POP3 on the mails.ha.

A cut off of a few seconds at maximum is to be expected.

Update(s):

We are always looking for the origin of the problem, which appears only on some very specific configurations:
IE 8, with SSL on roundcube.


Date: 2010-12-24 14:29:01 UTC
The download of attachmentes via SSL on roundcube
does not work for some customers.

The download without SSL works correctly.

We have identified another problem on the base of \"sticky\" on the ACE.
Some customers launched impossible connections on pop3/imap.
The problem is now resolved, we are closely monitoring the behaviour.

The limit of the base of the \"sticky\" was reached. We increased it.

That should solve the connection problem on ns0.

Date: 2010-12-16 11:42:30 UTC
We think we have found the origin of the problem: when the SSl client requests the re-negotiation of the certificate,
the connection is disrupted by the ACE, which does not authorize it.


A case example:

The connection is therefore cut off
