[New-bugs-announce] [issue3351] Python crashed

[yiyuan]

New submission from yiyuan <support at proxyshell.com>:

Hi,

I'm new here and I'm not sure whether this should be reported here.

OS: CentOS 2.6.9-67.0.15.EL
Memory: 512M
Python Version: 2.5.1

The crash happened after our web program writen with python running for
many days (maybe 20 days).

Here are the logs I found in /var/log/messages

What caused this problem? Run out of memory? Please tell me what I can do.
