Hi

Just new here.
Using the Percona Server for some time and all worked, but my SEO was good and the traffic raised.

With the raising traffic, I have some problems know with the percona server.

Server is a Athlonx X2 Maschine with 8 GB RAM, RAID1 System.
OS: Ubuntu Lucid
SQL Server is Percona Server 5.1 latest version.

Here is my config:

client]
port = 3306
socket = /var/run/mysqld/mysqld.sock

[mysqld]
user = mysql
pid-file = /var/run/mysqld/mysqld.pid

And now my problem.
MySQL Threads are sleeping and they not die.
From mytop:

758 root localhost ap24_v3 0 Sleep
1083 root localhost ap24_v3 1 Sleep
634 root localhost ap24_v3 2 Sleep
908 root localhost ap24_v3 4 Sleep
1085 root localhost ap24_v3 4 Sleep
1087 root localhost ap24_v3 193 Sleep
1086 root localhost ap24_v3 194 Sleep
910 root localhost ap24_v3 493 Sleep
760 root localhost ap24_v3 786 Sleep
638 root localhost ap24_v3 1079 Sleep

This is after 5 minutes of a mysql restart. It raised to 100 threads there are sleeping and Mysql runs out of memory.

Any Tipp or help would be great.
thx
