A web agent can cause the Apache Web Server to hang if the agent's log rotation fails. A log entry to report this condition has been added in the version 2.2–03 release.
Workaround: Make sure that the correct permissions are set for the web agent log directory and that the partition where the logs are stored has enough space. Additional considerations for this issue are:
To prevent permissions failures for the web agent's log directory, make sure all web server child processes have write permissions to the log directory. For example, consider the agent for Apache HTTP Server. If the initial Apache HTTP Server web agent log file is opened by super user (root) and the log rotation will subsequently be attempted by a child process running as a different user (such as apache user), make sure that apache user has write permissions to the log directory.
In case of log rotation failures due to write permissions, the logs will be written to the web server's error log file.
