Do a simple math. If you give each VM up to 384M heap and if you add
some 100 MB for permspace and overhead, you have a consumption of
500MB per VM. Take 1GB for OS needs, you have 15, and 15.000/500 makes
it save to run 30 tomcat instances max.
Since you experience the problems after some running

Hello Talha,
from a quick glance at your post, do you have the same 30 max threads

Because sending 525 users through 2x30=60 max threads seems a little

Which software are you using to produce the load? Does it keepalive
the connections?

Hello,
never heard of javamelody before, but it looks like nagios ;-)
Jconsole is definitely not a tool for monitoring.

if you want to have monitoring from outside the jvm, go for
nagios/munin/big brother/sister or whatever.
If you want to monitoring fr
I remember a more or less public discussion some time ago, that the
acceptCount setting is virtually worthless, because modern kernels
simply ignore it.

P.S. By ignore I mean that ServerSocket.accept(100) has no effect.

Hi,
if you mean this kind of monitoring:

On a site note... I have made the observation that the JVM is
performing best without any explicit gc settings. Most time explicit
GC settings just cause havoc (fixes s
Just a note, it will probably be easier for you to start a project on

Hello Jesse,
is the Workflow re-intrant? If yes:
this is odd:
you are iterating in a re-intrant action (i assume the action is
re-intrant) over a shared variable?
Vector vecOids = new Vector();
in the method:
Iterator oidIterator = vecOids.iterator();
P.S. Your tomcat is writing gc logs, please attach them next time.

Hello Kranti,
first of all I strongly believe in open source software and don't like
to obfuscate things. But well.
1. If you have internet connectivity on the target server you could
only deploy a skeleton of your application and load the

directly from your servers with o
Do you develop web applications and deliver them to the client, so
that they can install your applications on their machines without your
access to the machine?

of course there can't be a high-load thread without me, so here are my 2 cents:

I'm working in high-performance high-portal environment since 2004,
