I am not sure if this is enough info or not. I will try and monitor this for updates.

Here is what is dumped from Ruby:

I had similar issues with 1.9.1 p243 and upgraded to p376. I believe the issue moved slightly. I only see this when I do a particular operation but the operation is rather complex to describe but it does involve opening and closing sockets over time.

Also, a slightly annoying and possibly easy to fix characteristic of this is the application does not die. I have to kill it with -9 to get it to exit. It would be nice if it dumps out the info and then exited or produced a core file for later analysis.

Hi, Perry.

Could you please issue gencore to generate core file before kill command?

I would like to see top of 1MB of core file for initial investigation.
I just want to see resource limitation.

$ gencore
$ dd if= of= bs=1024 count=1024
and send it(output) to me personally. ([e-mail])

And some questions:

1. which compiler are you using to build ruby? gcc ? xlc?
2. let me know what kind of options did you use for configure?

Maybe I will ask snapcore or something later.
