the technical reason for this message is that your job has 
tried to write into an address space region that was set 
read-only. this can happen because of a number of reasons.

1.) you have a bad error in your input (most frequent reason).
2.) your compiler has miscompiled the binary.
3.) your hardware has a faulty memory module.
4.) you have found a bug in the code.

best regards,
