Re: Task process exit with nonzero status of 134
Anthony,

personally I haven't tested yet, jdk7 have bugs already. Was only a
hint to see if the error occurs.
I would focus on memory issues, the installed RAM are okay? No errors?
My next step would be to downgrade into one JDK earlier to check for a
bug. Did you update the OS before?
