Running close to the edge

[elor]

Hi,

I had a couple server crashes in the last week and I think it's available memory. Does this look strange to you with so many mysqld/mailman processes? I understand the 5 mailscanners, named and httpds, but I don't understand why so many mysql and python processes. Anyone spread a little light for me?

Thanks,

Dear elor,

Please try the script:

/scripts/fixmailman

The should fix the problem regarding Mailman.

Check to see if you have allowed persistent connections to database. That could be a reason why you see unclosed mysql connections.
