Issue/Introduction
When running a Policy Server this one might become unresponsive and
shows many log lines like :
[3632293/140440221234944][Tue Apr 30 2019 14:30:56][SmAuthorization.cpp:2248]
[INFO][sm-log-00000] Execution time exceeded threshold.
(CSmAz::ProcessActiveExpression, 6928, 5000, agent=myagent client=*10.0.0.1
server=https://myserver.mydomain.com resource=/myresource/image/image.gif action=GET user=)
Cause
When running Policy Server Trace Analyser against the Policy Server
traces (1), the top 2 processes that consume the maximum time are the
ones concerning CRL verification :

Looking at the Normal and High Priority queues, there are only 0 or 1
request in each queue, nothing more. That means that the Web Agent has
big chance to fail to the next Policy Server because the request is
taking much too long time to process.
Environment
Policy Server 12.8 on RedHat 6;
Resolution
Upgrade the Policy Server to 12.8SP3 to get the fix for CRL processing (2).
