We're running Policy Servers, and suddenly we see them starting
experiencing High CPU consumption. This results in Web Agents were
unable to connect to the Policy Server.

We've changed nothing to Siteminder environment.

How can we solve that ?


Policy Server 12.52SP1CR02


You have taken some pstack from the Policy Server process at the time
of the issue.

The stacks show a known issue occuring in the Policy Server 12.52SP1CR02. 

This issue occurs when one or more users belong to circular groups in
your User Directory.

Let's say : 

user1 is in group 1, which group belongs to group 4, group 4 to group 
5, and group 5 belongs to group 1 : This would be circular group ... 

Previous to Policy Server 12.52SP1CR04 this kind of User Directory 
configuration brought the Policy Server to consume all the available 
CPU cycles. 

The stack reported from your environment match the pstack that have 
been analysed in the fix :
