Details

(Keywords: meta)

We have a number of IPC "serialization" or "deserialization" errors which appear to be caused by a shared memory region which has been successfully created & mapped failing to be used (e.g. with a dup syscall) with EBADF (9). It's unclear how this could be happening, so this bug is to track the specific crashes, and keep a central record of possibilities.

The most likely is something like FD exhaustion, though it's surprising that DF exhaustion would produce a EBADF error code.
