Jobs crash with error forrtl: severe (174): SIGSEGV, segmentation fault occurred

Reported by: feturner Owned by: um_support
Priority: normal Component: UM Model

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

  • UM Version set to 4.5

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
