I had an inquiry on this error from another Clovertecher so I thought I’d post a follow-up…
The EXCEPTION_ACCESS_VIOLATION occurred several times but only presented the -901 once that I know of.
We brought up a new set of interfaces that included some Tcl code to start and stop threads. A panic would sometimes happen when a pstop or pstart command was issued. My best guess is that stopping and starting threads frequently causes a memory leak in Windows and eventually results in a panic.
The workaround was to set up a .cmd file to bounce the process twice a week. We haven’t had a panic in three weeks but I still have the engine output turned up just in case.
