FYI: Backups fail - Too many open files - caused by too many threads.

MSP360 Backup Backup Mac
1

MacBook (2.9GHz 6 core Intel i9 w/ 32Gb RAM) with Catalina. Back up plan was working, now only the plan config gets backed up. Created new Plan, selected Macbook HD / volume, set defaults, same behavior. Rerunning the backup, results in an internal error.

Both agents have the same behavior:

Backup agent; v2.10.1.26
Backup agent; v2.10.1.36

Latest excerpt from the log:

Log file:log_worker_{df57a5bf-b406-4349-ae78-19d89387efd7}.log:2019-11-10 18:55:40,445557 [ERROR]: [ CBC ] [ 61 ] Error on load MBS Cloud plugin, message: Too many open files

Mac OS ulimit:

ulimit -u 5568

Max thread count had been set at 50, reduced it to10 and backups started working again.
