Frequent too many MySQL connections error
| Posted by Kailash12, 07-02-2010, 01:22 AM |
| Hi,
I have a shared server running on Windows 2003 (32-bit) and MySQL 4.1 server. I frequently receive too many MySQL connections error. This is a shared server and there are around 300 websites and 50 MySQL databases are hosted. Can you suggest a tool to monitor the MySQL usage and connections?
Thanks,
Kailash

| Kailash,
You can use the following command from the command prompt to monitor the mysql usage.
'mysqladmin -i3 processlist -umysqluser -ppassword'

| Current limit is 800. It seems there is some bad written scripts on the server. Do you suggest installing any mysql monitoring tool?
Thanks,
Kailash

| Will give the process list. There are also many tools available in the market which has GUI interface too to monitor the mysql process like http://www.webyog.com/en/

| You can increase the system-wide connection limit in the my.ini file, but you should first try to find the offending website. It sounds very like bad code that is opening a new connect for each query. If you can't get them to clean up their code, you impose connection limits just for them to protect the other users.
