Has anyone come across situations where an SSL module (CSS5-SSL-C-K9) stops responding and users get "Page connot be displayed".
When you try and look at the SSL statistics (sh ssl statistics ssl) you get the following error message:
Timeout waiting for SSL_SHOW_MSG response
Accessing and interrogating the redundant CSS, with the same command, was not a problem. There was no failover as, I suppose, this would be regarded as a "soft" failure (i.e. all critical services and the SSl service itself were OK).
The was no indication of any issues being reported in the traplog or sys.log. A few days previous to this event occurring I had amended the set-up which necessitated doing extensive re-configuring, suspending and re-activating the SSL proxy-list.
We have dual CSS11503, running 08.20.2.01, in a Master/Slave redundant set-up.
Given this error message and your CSS version information, you might be hitting a bug. There is a bug that you can look online using the Cisco bug tool kit for this bug "CSCsm50650 - Header insert can cause the SSL module to become unresponsive". If you have configured http-header insert under the SSL proxy list, then this bug is applicable in your scenario.
Mostly rebooting the CSS should resolve the issue. I would recommend you to open a TAC case if this issue exist after the reboot also.
I was just looking for the bug information based on your email. I have not seen much issues regarding to the error message that you received. It is always better to be on the latest version on code as far as possible.
