mod_fcgid

[keny]

Hi i am running lastest version of plesk on a debian 6 machine.

My server is very slow now and in my apache log i see that :

I do beleive that mod_fcgid is the problem but i don.t know what to do !
What other log i have to check for error if this is not the problem ?

Thanks

Are you under a dos attack? You can check this with:

netstat -plan|grep :80|awk {'print $5'}|cut -d: -f 1|sort|uniq -c|sort -nk 1

Will show you the number of connections per iP address connected to your server. If you are dossed, then you would install dos-deflate to help mitigate the attacks.

Thanks for reply,

No i dont think it was a dos attack, i have solved my problem by restarting my server but problem will recame for share,

I check my server stats before retarting and my memory was use at 99% (16GB) and my swap memory was use 100% (1GB)

There really something going wrong on my server and my log just keeping with mod_fcgid error ...

any ideas ?
