Apche hangs ever few minutes after an update
 
Hi,

I made Debian package update/upgrade and since then my apache hang every few 20-120 minutes. and I have to restart to make the site available.

I tried to find the cause, but with no luck (I;m not an linux expert:o)

here is my apace error.log:

Code:

*I censored some sensitive information in the log.

I think apache hangs after killing so many child process. but I don't find the solution for this.

Thanks

Not sure what's causing this, but you can use monit to automatically restart Apache if this happens: http://www.howtoforge.com/server_mon...debian_etch_p2

Thanks for the suggestion. It's a great temporary solution.
