Okay this errors i get when there are too many connections or the memory is out of resources.

The question is, can i limit the connections and memory for each user?

If so, can someone tell me how to do this? I have full root access.

plz help. i have too problem...
many sites is down!

 

[rohit]

you also might need to investigate that why that large site is causing the issue. It could also very well might be because of poor coding?

Just in this case, I would say that for a time being (INTERIM SOLUTION) buy a separate hosting for that large site somewhere and move it to that server. In this way you can have your other sites running. Just My Suggestion!!

im trying to find a way to limit apache memory usage as well. the way the default config is with da it will fork bomb in a heartbeat under massive connections
