Hi dude

I'm quite newbie with Glassfish, but I have this question. A customer of mine asks me to help him in Glassfish tuning. This is the environment:

Hardware:
- VmWare virtual machine
- 4 cores
- 16Gb Ram

Software:
- Ubuntu Server 14.04
- Java JDK 1.7 latest
- Glassfish 3.1.2.2
- Oracle connector ojdbc1.6

It seems correctly running withour errors or warning.

To configure and "tune" Glassfish, they followed this how-to:

http://jfarcand.wordpress.com/?s=glassfish+production+essential+survivin...

In this instance he runs 2 glassfish domains in which they tried to deploy 12 EAR. During this deployments the system slows down progressively until it locks after the twelfth deployment. They need a reboot.

I know that could be useful to print some log files to know more about the problem, but unfortunately I don't have them at the moment. What I interested to know, at this moment, is what you think about this use of Glassfish. As I said, I don't know Glassfish well, but it seems to me that they try to use an application server not in a correct way (a lot of EAR, only one machine, two standalone domains).

What you think about that?

Thanks in advance for your help.

Daniele

You probably are running into the known classloader memory leak documented here:
