Jconnector / Apache / Tomcat problems

Hi all,

Could someone help me with some clues/advices or something?
I'm not an advanced linux/programmer whatever and I do not know what to do.
Hereunder are some details.

The web is working very slow and if I restart tomcat, one service is not closing.
There's only one thing left (for me) to restart the whole server.
After restart, the database is working but after a while (1H or two) it starts to work slow or not work at all.

[root@xxxxx bin]# ./catalina.sh stop
