VM running solx86 platform will crash immediately when stack size set to unlimited.

Customer report this problem when they try to submit simple java application
through SunONE GridEngine. By default, SunONE GridEngine set stack size to
unlimited in execution hosts. Customer will always see this crash if they simply
accept the default value.(most customer just accept default value)

To reproduce this bug:
1. Login to a solx86 machine
2. set stack size to unlimited
   $ ulimit -H -s unlimited ; ulimit -s unlimited
3. run java -version

Hi,

just FYI, the reason for the crashed Java app was the "infinity" resource
limit setting of the queue.

I'm wondering how someone can write a software which crashes when the stack
size is set to infinity? All kind of software and any OS version seems to be
vulnerable, Java, simulation apps on Linux, an older version of the IBM C
compiler on AIX...

This is a good example where you really don't know of such a problem is
related to the operating system or not. Probably the customer will tell you
"it runs on XYZ, but crashes on ABC" and you easily might focus your support
efforts on the wrong area;-)

Andy,


Thanks for the update on the alias I have corrected that in my mailtool. I
recevied word from cu that setting the ulimit values to what the shell was
outside od SGE worked for him. They were happy and gave the OK to close the
case.

Thanks

}I have a guess which turned out to be true in many similar cases: By default
}the SGE queue config sets all Unix resource limits to "unlimited". Some
}applications seem not to be able to handle an "infinite" stack size.
}
}Try to either configure "standard" limits in the queue config or add
}"ulimit" calls for hard and soft limits in the script before the application
}is called (just use these values you get with "ulimit -a" and "ulimit -a
}-H" in the user shell).
