[HTCondor-users] WANT_HOLD condition does not work on Windows

[Serafim Urukov <serafim.urukov@xxxxxxxxxxxxxx>]

I am experiencing a problem with WANT_HOLD configuration on Windows. Originally it was like this

    # Limiting Job memory consumption.

    MEMORY_EXCEEDED = ((MemoryUsage > Memory) =?= TRUE)

    PREEMPT = ($(PREEMPT)) || $(MEMORY_EXCEEDED)

    WANT_SUSPEND = $(WANT_SUSPEND) && $(MEMORY_EXCEEDED)

    WANT_HOLD = $(MEMORY_EXCEEDED)

    WANT_HOLD_REASON = ifThenElse( $(MEMORY_EXCEEDED), \

                strcat("Memory limit exceeded: ", eval(MemoryUsage), " MB > ", eval(Memory), " MB"), \

                undefined )

This part of config works as expected on Linux, but neglected on Windows. I supposed that is related with config syntax, but there is no errors traced in logs.

Moreover, even if I set literally WANT_HOLD = TRUE, nothing happens. I haven't found something related to "platform specific" for this case.

My job is a demo script that consumes about ~1 MiB of memory each 0.5 s.

Expected behavior: when job uses a lot of memory it should be stopped by WANT_HOLD.

Real behavior: job runs infinite, OS Windows even involves swap memory.

OS: Windows 10 Pro 21H2 19044.2251

HTCondor: 8.9.11

Does WANT_HOLD work on Windows?
