Thank for ur reply.We have found the problem.The problem is 15 days back to tweak mysql perfomance we have made changes in my.cnf to allocate more memory to mysql and restarted mysql.we didnt restart httpd that time.
When we restarted httpd last week the problem started.There is memory allocation for apache.
when we restored with old mysql configuration my.cnf the problem stopped happening.
Server IBM x3400 with 2gb memory.30- 40 concurrent users accessing the server(Hospital Management System Application).
database details:
456K marthasbloodbankv2

Can you give me some suggestion to increase the perfomance of the server.
Thanks and regards,
