[FLASH-USERS] SIGSEGV 174 error in Flash 4.5

[Plechaty, Christopher]

To all,

 

I am experiencing a SIGSEGV 174 error that I cannot seem to figure it out. 

 

I have been running the lasslab example (in 3D) which has been modified for
my purposes. The simulation runs great, and happily dumps restart and plot
data files for a long time. However, after some time, FLASH decides to write
a restart dump and suddenly crashes due to a SIGSEGV 174 error (placed
below). 

 

I am running:

Flash 4.5

Intel compliers and mpi (2018)

HDF 1.8.13

Hypre 2.11.2

 

My cluster runs Centos 7. 

 

The error is as follows:

forrtl: severe (174): SIGSEGV, segmentation fault occurred

Has anyone seen this type of error before?
