We're running Policy Server, and since two days, we experience heavy slowness on some of our Policy servers. We are getting at the time of the issue messages like : Connection request rejected. Connection limit of 3072 exceeded [Sm_Auth_Message.cpp:511][INFO][sm-log-00000] Execution time exceeded threshold. (CSm_Auth_Message::ProcessMessage, 19953, 5000, agent=myagent client=*10.10.10.10 server=https://myserver.mydomain.com resource=/index.html action=POST user=) How can we fix this ?
Indeed, the 1024 is too low, if you have set the Max Connection to 3072 and if this is a Production Server with load. From documentation, we mentioned that value but only to illustrate how the command to set it work. Modify the Default Limit Parameters https://docops.ca.com/ca-single-sign-on/12-52-sp1/en/installing/install-a-policy-server/install-policy-server-on-unix/prepare-for-the-policy-server-installation
Set the value of ulimit -n to a value much higher than 1024 to fix this issue
