In fact we have problems in one of our servers, and still We got more error msgs :
1- Fatal error: Maximum execution time of 30 seconds exceeded
2- 500 Server Error
The following error occurred: [code=SERVER_RESPONSE_CLOSE] The server closed the connection while reading the response. Contact your system administrator.
Could not open error file.
3- Database error :
mysql_connect() [<a href='function.mysql-connect'>function.mysql-connect</a>]: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (11)
4- The server load average: 24.80, 11.18, 4.87
And still inrease.
So, please provide us with the resovle for theses issues.
With high loads like that, I would be looking at all the processes on the server to find which one(s) are causing problems (either use top or ps aux).
Something is obviously eating more than its fair share of system resources, whether it be a spam attempt, badly configured service, or something else. You just need to find it. Good luck!
