I'm trying to track down some problems involving random channel kills. I am getting intermittent channel hangs with no error messages present. In order to try to track down the problem I inserted code in FW_ENTER and FW_EXIT tracking each call to Foxweb. Upon entry I log the calling script and query string as well as IP address, foxweb channel, agent and a few other items. Upon exit (FE_EXIT) I log the elapsed time and so on. By looking at the log I can see which script calls do not ever execute FW_EXIT.

 

The problem is that when I then execute the script called with the given query string there are no hangs. So I cannot reproduce the problem. Most of these scripts have been running for 10 years or longer. They do not contain any illegal commands, etc. The Fox Web start log is not much help.

 

I tried adjusting buffer memory and a few other random tweaks to no avail.

 

Can you suggest any other methods to try to pin down what is causing the channel hangs? It's not a critical problem in that the channels do restart but I would like to know what is causing the problem.

Thank you.
