Description
Hi,
Two of my jobs (xocdg and xodje) keep crashing immediately when I submit them to ARCHER. When I look at the crash file, it says the error is
forrtl: severe (174): SIGSEGV, segmentation fault occurred
I can't find much info online about how to fix this - is there an easy solution?
Thanks,
Fiona

Hi Fiona,
Segmentation faults mean that a disaster has occurred in the model and it is now trying to write to prohibited areas of memory (e.g. where your executable code is). Usually they occur because a prior error has gone unnoticed.
I can't seem to find your .leave files for xocdg: the only one available is in um/umui_out and that is dated more than a month ago. Also there seems to be no pe0 file in today’s run in /work/n02/n02/fturner/xocdg.
It's difficult to say more without looking at the output.
Regards
Willie
