[ncl-talk] Segmentation Fault

[Jonas Lauer]

Dear NCL Community,

we have been happily using the ncl software for a couple of years already. Lately we regularly are confronted with Segmentation Faults for one of our scripts. The NCL script is called from a php script and works on grib files of 1.7GB.

Error message:

	Calling NCL
Executing: export NCARG_ROOT=/PATH_NCL/ncl; export PATH=$NCARG_ROOT/bin:$PATH; cd /WORKING_DIR/euro4-plots; ncl 'ini=2019041700’ eu_read.ncl
    sh: line 1:  2596 Segmentation fault      (core dumped) ncl 'ini=2019041700' eu_read.ncl
		
	There is no further information. As the same script has been working for a long time already and the second attempt with identical inputs worked, I would assume that there is no scripting problem.

Technical info:

	NCL version: 6.3.0
	OS:	CentOS Linux Version 7
	
	At times we run several NCL scripts in parallel, might there be some confusion with temporary files? The processes run in different working directories.

Maybe somebody was confronted with the same issue already? I am very glad to give any additional information if required.

Thanks in advance and best regards,
Jonas
