[mapserver-users] Too many open files...

[Lee Meilleur]

The problem ended up being an issue with ulimit, the parameters I entered were not taking.  I found the page below which seems to have resolved the issue.  Thanks again for all of the suggestions.

Lee,

I think I have run into this before.
Turn off SELinux if it is running and I bet that is it.

Otherwise, try building mapserver from source, maybe you ahve a library or rpm packaging issue.
