Poudriere "bad file descriptor"

Hello.

I run Poudriere on an amd64 server (8 cores Ryzen 7 with 32GiB of RAM 
and ZFS RAID5 on enterprise SSDs) which has always worked fine.

Since I upgraded to 13.2, my bulk runs often err on some port.
I looked in the logs of the failed port and always find the cause to be 
a "Bad file descrptor"  message.

Partial example from devel/pyside2 (but it's not always the same port):

Then the bulk continues, obviously skipping all dependent ports, but 
still building some hundred.
Then, if I start the bulk again, ti usually works properly.

I thought perhaps memory was at stake, so I looked into the logs to see 
if any process was killed out of swap space, but it wasn't.

Anyone else seeing this?
Any hint?

  bye & Thanks
