What does "rejected by signature hysteresis" mean in an Apple log?

I've got a bunch of programs that are not responding normally when traversing a folder tree inside an array formatted as RAID1, RAID4, and RAID5. There are no error messages, but each time one of these programs fails to connect with the folder and its subfolders and exits normally, the diagnostic log shows the same error "rejected by signature hysteresis". "rejected". Error 312.

Since this only occurs with some programs accessing the same drives, I'm being driven batty trying to figure out what the problem is.

Does anyone have an explanation so I can continue to search for a way to workaround this issue.

This is occurring in Ventura, Beta 11 (it may have begun in Beta 10, but I'm not 100% certain). There are at least 8 relatively common programs from different vendors involved.

I'm running a Mac Studio Ultra - 20, 48, 32 with 64K RAM
