Hi All, I have two servers, one is centos 4.3 (new) and other is rh9 (old). Both of them run mysql as the primary database server. I installed mysql via the rpms available in mysql.com downloads. Recently when i do "pstree", i noticed that RH9 server shows many mysql children while centos shows only one. Here is the pstree result. (Both of them runs the same version of mysql) server A (RH9 , MySQL-server-4.1.19-0.glibc23 ) --------------------------------------------------------------------- ├─mysqld_safe───mysqld───mysqld───13*[mysqld] and server B (CentOS 4.3 , MySQL-server-4.1.19-0.glibc23 ) --------------------------------------------------------------------- ├─mysqld_safe───mysqld my question is, why mysql is showing one process in centos?. I use same my.cnf in both servers. So i believe it is not a config issue. I believe someone can explain it to me. Regards, Renjith Rajan
