Hi Naveen,

Was noticing something like this while testing last night, but hadn't
gotten around to determining if it was in master or just the branch I
was testing.

Are you seeing this even if rpc = False?   I noticed this only when my
settings got reset to make rpc = True, though I haven't investigated
it enough to know if that is the rpc flag is just a coincidence.

Another possible correlation I've noticed is that it occurs when I use
a script to spin up multiple VMs in succession, possibly suggesting
some kind of race/timing issue.  Does that match your use case?

It looks like there's a bug on this, so I'll post my questions there
as well, so that we can keep all info on the bug in one place:

Thanks,

Dan
