Description

Duane reports that there have been longstanding problems with stability of the node NBPMOV (Numi Orbit Verification) and his investigations point to the file
libpmctrig-3.2 as what causes the node to fail. The node will require rebooting sometimes as often as once per day (or 2 or 3 days) when it is running with that object file.
Duane states that nbpmov operates with interrupts at 1 kHz, which is the only thing that distinguishes it from other similar nodes. The system clock hasn't been modified and is still slow (60Hz).
He had a serial terminal attached to it across multiple outages, and nothing interesting was printed to the terminal (e.g tasks dying). But he added a diagnostic memShow printout and there
looked to be a memory leak.

He's currently running with the older libpmctrig-3.0 and has no problems.
