SSO not working when VMC is activated

Hi all,           

I hope someone can help me. I am trying to implement SSO for SAP ABAP systems using our own PKI server along with NW SSO 2.0 client. Figured out all the steps and got it working in most of the systems. But in some of the systems where we have activated VMC(Virtual Machine Container) SSO via SAP GUI would not work. Webgui using SSL protocol works just fine. Only when I try to log on using SAP GUI(SNC enabled), it throws a message   "SAP System Message" without any details. On server level the Work Process restarts itself with  following in the system log:

Signal 4 received by operating system Stop Workp. 12,PID 14090342

Signal 6 received by operating system

Error handling canceled

Signal 11 received by operating system Error handling canceled

Start Workp. 12, 8 times since system startup. PID 14090344

Delete session 001 after error 023

As soon as I disable (vmcj/enable=off), SSO via GUI/SNC starts working fine. Please help.

Such kind of problem should be analyzed in the effected system - since it's hard to reproduce them without knowing the exact version of OS, ABAP kernel, SNC library (on the ABAP server side) and VMC libraries.

Can you kindly report an incident?
You can paste the incident number in this thread, afterwards.

This incident has not reached Development Support, yet.

But since I'm now aware of it, I'll pull it.

The incident is on "customer action" since July 10th.

It seems that you are using an outdated SNC library version.

The current processor has requested to update the library and to create traces if the problem still persists with the new library.

Please follow-up on the incident rather than posting to the forum.
