Linux server is slow

Hello,

I am using Redhat redhat 4 update 4 kernal 2.6. My server is some time suddenly running slow.
The averge cpu load goes up to 50 to 60. (There is only two CPU and usually, the averge load
is between 1 to 2.5) That time, i see, there are several sessions connected.
Normally, we have 150 to 160 session. But when the server is slow, the total number of sessions
goes up to 400. At that time, it is taking long time to connect into the database. Even,
connecting into linux box is taking long time.

Our application server is showing this error message in log file.

ERROR] [2008-10-02 13:09:31] [JDBCExceptionReporter] The data source returned null from getConnection(user,password).
org.hibernate.exception.GenericJDBCException: Cannot open connection

Any one is phasing this problem??? Any direction to pursue this issue?
