Error with wclock_on subroutine

[ckerry]

Hello,
When running ROMS I am getting the following error. I'm wondering if anyone knows what it means and how I might debug it.

[gadi-cpu-clx-2186:757301:0:757301] Caught signal 11 (Segmentation fault: address not mapped to object at address 0x200)

etc etc... for all 48 cores

It appears that some variable that wclock_on is trying to use is not defined.

Thanks ...

If you recompile with USE_DEBUG you should get some line numbers in the error report. Those line numbers refer to your files in the SCRATCH_DIR, so it helps if you go looking there to find out say which call to wclock_on is failing.
