Pavan, This machine is exclusively used for Apache and Tomcat. There are no other major services running on it. No other services are taking up more memory. When Tomcat hangs, there is still a lot of physical memory available on the machine.
There are no scheduled tasks running on the machine. - SPS Content-Type: multipart/alternative; boundary="=_alternative 00443A1185256E63_=" --=_alternative 00443A1185256E63_= Content-Transfer-Encoding: quoted-printable Content-Type: text/plain; charset="ISO-8859-1" also pls check if u have schedukled any tasks in wndows like virus scanner = etc etc..they consume a lot of memory and effect the performance...
