Is getting more memory for this machine is my only option?
Is playing around with -X?? options of Java will help me, Solaris is
supposed
to do good job of handeling virtual memory. Or is it aleak some where in
Java/Tomcat.
I did my home work and searched the archive and found similar issues but
for Windows, so it have difference solution/reasons.
Thank you all in advance.
