Performance issue with JVM (1.6.0_22) invoking OS command on Solaris 10

My high-level problem is my build tool (Maven) which became suddenly very slow on a Solaris 10 environment. A build which was taking 8 minutes now takes 50 minutes.

I narrowed this problem down to a maven plugin repeatedly calling

Runtime.getRuntime().exec("env");

This makes the JVM (version 1.6.0_22) invoking "env" command on the OS.

Each one of this calls takes approximately 1.5 second versus a few milliseconds on other Solaris 10 machines.

A reboot of the machine helped once and things became normal again for a couple of weeks. Now it's gone bad again and reboot doesn't help.

Thanks

Solution 1:

It may be bug 6970542

Try setting:

export DTRACE_DOF_INIT_DISABLE=1

I've seen that problem on a number of test machines which were working normally and then started to get really slow startup times. On JDK 1.6.0_26 it works properly again.
