High Memory Utilization

Hello Guys,

I have one Solaris server with high memory utilization >90%. As per checking, below is the output for memory usage.

Code:
bash-3.00# ps -efo pmem,uid,pid,ppid,pcpu,comm | sort -r

 0.1 267074 20722 20717  0.0 /opt/web/apache/app/team/bin/httpd

As per further checking, there was more idle process that I suspect to be the reason of high memory utilization on the server.

Can someone advise on this matter (on how to reduce the memory usage utilization)?

Thank you.

BR,
Mr. M Smilie
