Description:
Hello,

This is similar to bug# 16995. Mysql process remain in sleep state even if the timeouts are set in /etc/my.cnf file. The variable mysql.allow_persistent is set to Off. 
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Mysql version: mysql  Ver 14.7 Distrib 4.1.22, for pc-linux-gnu (i686) using readline 4.3
Linux kernel: 2.6.24.2.dn.p4 
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I searched for a fix but could not find any. Please help.

Regards,
Anu

How to repeat:
Steps to recreate the issue:
mysql>
set global wait_timeout=10;
set global interactive_timeout=10;
mysql> show processlist;

Once you find that there are processes that remain in sleep state for more that 10 seconds, kill one of the processes

mysql> kill <PID>;
mysql> show processlist;

Now you can see that all the other processes that were in sleep state have got removed.

Many thanks for writing a bug report.
MySQL 4.1.22 is quite old. Please try our newest version MySQL 5.0.51a or even 4.1.23 and let us know if you still run into this problem.
