I have problems with VisualVM 1.3.4. It says cannot connect to admin. My connection is fine, and firewall is set too.

What could be the problem with this?

Visual VM 1.3.4 error connection problem to admin

Hello Chris,

The error you're getting is possibly due to a JDK bug taking heap dump which is crashing the target JVM in case it is running JDK 6 Update 16+ using Concurrent Mark Sweep garbage collector (CMS).

To resolve that issue, you will need to use a different GC , for instance -XX:+UseParallelGC. The same issue may affect the JDK 7 devbuilds.

Regards,

Carl

Visual VM uses some code coming from JDK tools and it have a really lightweight feature for profiling. VM alone is a visual tool and the designer design it for production and development purpose. Aside from the above information, Visual VM can be used to monitor Java SE also do performance analysis to it. From your error message it seems there is connection lost and it can be from the VM software or it might be another program that is blocking the connection

Using the proper operating system will help you to operate a software without a problem, if you use other OS for this, you might need to give it up, here is the list:

Microsoft Windows (7, Vista, XP, Server): 32 bit & 64 bit

Linux: Intel platform, 32 bit & 64 bit

Sun Solaris: Intel & Spark platform, 32 bit & 64 bit

Mac OS X: Intel platform, 32 bit & 64 bit

HP-UX 11i: PA-RISC platform, 32 bit & 64 bit

Hope the best for you
