Certificates vanished - ACE Module. Strange!

Answered Question
Mar 5th, 2009

ACE modules are configured in Active/Standby context mode on two distinct Cat6500's. The feature license is 10,000 SSL tps, 8Gbps throughput.

We ran the application performance tests with 1000 users with https transactions and I noticed that the all the root certificates under the chaingroup disappeared. Only the website certificate remained. When I accessed the website, it gave 'error with the security certificate' i.e. the root was not identifiable due to missing certificates. Eventually, the CPU went 100% on Cat6500 and the ACE module was shutdown by the chassis. It got reenabled automatically in 5 minutes.

I re-added the root certs, removed/added the service policy and after sometime I noticed the root certs disappeared again. STRANGE !

Could you please advise whether there is any bug in the above software version i.e. it removes the root certs due to heavy transaction load.


I have this problem too.

I have downloaded the A2(1.3) version but I am not able to find any release notes detailing bug resolution list etc.

Also, can I do a direct upgrade from current version to A2(1.3).
