I am configured with the same problem.
Sometimes, my JBoss starts when I launch it the first time. Sometimes I have to try 50 times!
Usually, it workes after 5-10 times.
I'm running JBoss 6.0.1 EAP under Windows 7 64bit.
Can anyone help?
for me it worked to use the recently released JBoss version 6.1.0 EAP.
