Issue/Introduction

I have an Apache 2.2 server protected with a Web Agent, and we are seeing the following entries in the Apache error logs.

[Info] [CA WebAgent IPC] [4068] [CSmIpcEvent::WaitForEvent] Time-out interval elapsed, but the event's state is nonsignaled

What is the meaning of these messages? Can they be ignored?

Resolution

This message means that an internal event that SiteMinder Web Agent is using, is not yet signaled within the time interval expected. This message can be produced from various places within Web Agent code and it is part of normal operation of Web Agent.

Those messages are informational only, and they can be disabled by modifying trace.conf file as per the following documentation:
