suddenly, I'm getting this error:
/lib/libc.so.7: Undefined symbol "xdr_accepted_reply"

Very mysterious: It showed up on a running system, which worked
flawlessly for some hours. And that host has root-fs (/) mounted
readonly from a memorydisk. So to my understanding, it's completely
impossible that /lib/libc.so.7 is corrupted since last boot.

I'm completely out of ideas what could cause this strange error during
"normal" operation.

Normal operation in this case is serving as a bhyve test machine.
I first noticed that error after one guest - with passthru device
attached - was shut down.

My suspicion is some undiscovered passthru interference... Since I
noticed one other _very_ strange passthru-effect:

Thanks for any hints,
