I wouldnt leave the troubled circuit as is, best to get it fixed.
rather than leave a unknown issue hanging. since no one knows exactly
whats wrong it could be a larger problem, and cause a fire in the
future......

I unplug everything on any circuit that repeatedly trips a breaker,
its free easy and fast. plus it narrows down the issue. before paying
for a electrician its a good idea

one thing the pop means whatever it is is a dead short, which is
easier to find than one that trips occasionally, for no apparent
reason. I hate intermittents
