Hi,
Running OpenSAF 4.5.1, at system initialization we can have a race condition on
our payload cards between OpenSAF startup and housekeeping functions that
update the system time.
If the system clock is updated at the wrong point, the time check loop in
immModel_cleanTheBasement decides there was a timeout.
>From our logs (the time jump is due to the clock set, not a gap in processing)

I am working to change the startup sequence to avoid this jump, but
immModel_cleanTheBasement is using time(NULL) to get current time and comparing
it against cl_node->mLastSearch. Where time() works back to CLOCK_REALTIME, it
would seem there's always possibility of a problem, maybe that could change to
use osaf_clock_gettime(CLOCK_MONOTONIC... instead?
The side-effect of the timeout is that osafamfnd aborts and neither restarts
nor triggers any recovery action, so the system sits until our external
watchdog kicks off a reboot. Is there a way to configure the system such that
it cleans up and restarts?
Thanks,
Andy Riley
