in _my_ source code, drbd 8.0.6,
the line 374 does only contain an if statement.
the line 376 is a BUG_ON statement.
so maybe you want to be more precise about what version
you actually are using, and what that "panic" looks like?
or is is the BUG_ON statement?
could it be that the cause of the problem happen much earlier, and is
about some memory shortage, which you ignored?
what is in the kernel log,
from the start of the drbd until the "panic"?

that is a very small max-epoch size.
you don't want to do that.
but that is unrelated.
