Re: Multithreaded Server Crashes under heavy load

First pass: Change use threads; to use threads stack_size => 4096; and see if things get better.

Next, use whatever tools are available on your system to instrument memory, cpu and socket activity for the process as it is running and capture it to a file. Make that log (sanitised as appropriate) available on line and post a link to it.

Made the change to use threads but it produced the same result. Looking for a tool to use to capture the information requested now. Is there a tool that you could recommend that can capture all of that information on a Windows environment? Thanks.	[reply]

Is there a tool that you could recommend that can capture all of that information on a Windows environment? Yes. Type `perfmon.exe` into a command line. There is a bit of a learning curve involved in using it, but it is gui with pretty extensive help built in.

Ok, so heres the link to the comma delimited CSV file perfmon generated. Did not see how to get it to generate socket information for a specific process though. Also, the thing doesn't show that perl ever reached 100% cpu usage, but using the task manager shows that it spawns multiple perl processes, and that cpu usage is maxed for a while, eventually all but one perl process disappears from the task manager, cpu usage drops back down, and then the program is unresponsive. https://dl.dropbox.com/u/19686501/RXD_000006.csv Made this log by adding a new counter log, and then adding various process counters. If this was incorrect let me know.	[reply]
