Hi all,

We were using a java / jboss based application server that was running on RHEL4 perfectly well.. The java version used was jdk-1_5_0_03-linux-i586-rpm .. The memory utilization was good.

Now we are running the same application on RHEL 5, the the memory utilization is very high.. the free memory is very less. The Java takes up double the memory it used to.

Are there any compatilibty issues with this particular version of JAVA and RHEL5? Should I upgrade to a higher version of java?

Please help !!

Thank you,

regards
Johney

Have you set the Java command line parameters that allocate meory for the Java virtual machine? Sometimes you need high values so that applications can run at a reasonable speed - especially if the applications are memory hungry (or possibly badly written!).

The version of Java you have quoted has been superseded, so you may want to upgrade to jdk-1_5_0_14 - available from the Sun website: http://java.sun.com/javase/downloads/index_jdk5.jsp

I hope this helps in some way.
