Is it possible to determine what's causing PSSE 35 to crash via logging or another method?

Hello, I currently have a python script that's using PSSE 35 to test contingency events that seems to crash at random. Occasionally the script works, occasionally the script crashes. However, I'm rather certain the script itself is not what's unstable. Instead, it seems as though PSSE 35 crashes randomly while processing a contingency. However, it's not the same contingency every time, and as stated, sometimes it just doesn't crash at all. It doesn't seem as though it's a physical resource issue, like consumption of too much ram, and it occurs on multiple different computers. I was wondering if there was any way for me to log or otherwise find out what's causing the crashing issue. Any help is appreciated, Thank you!

Search this forum for "Crash" to get relevant information.
Enable logging from the start of the simulation (psspy.progress_output(2,"my.log",[0,0] or in the GUI, set the PDEV to file in the "I/O Control" menu)
Since there are contingencies that do not crash, the dynamic set up appears to be ok. Select one contingency that crashed and follow the steps in the post "Simulation Crash at Fault Creation"

You can also use psspy.ioflush() to force writing the progress output buffer, etc to the file. Sometimes it's helpful to add this right before a problematic script line to see what's happening right before a crash.

running pss/e from the dos command could also give you an insight of why it is crashing, also 35 now has a new tool called VERBDEB Option which could point you to the model which is potentially causing a crash.

You can also run psse from the dos windows, sometimes it tells you there where can be the problem.

I have experienced PSS/E 35 crashing, especially when working in SLDs and selecting all buses together. Already conveyed feedback to Siemens. If you have open SLDs, may try after closing them. Regards, Chandresh
