Linux Incremental Files Backup Keeps stuck on indexing

I’ve been using this software for something without issues.
Now two of my machines (they were running 2.4, so I upgraded Client and server to 2.5 and the problem persists) are forever stuck on indexing…

I upgraded by compiling 2.5 from sources over the 2.4. The installation seemed to complete successfully

SERVER: Linux xxxxx.xxxxxx.xxxx 4.19.0-23-amd64 #1 SMP Debian 4.19.269-1 (2022-12-20) x86_64 GNU/Linux

CLIENT: Linux xxxx.xxxx.xxxx 4.4.0-210-generic #242-Ubuntu SMP Fri Apr 16 09:57:56 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

Client log keeps saying:
2023-04-03 21:54:35: ClientService cmd: PONG
2023-04-03 21:54:43: ClientService cmd: #IJnqQeqDPtrpUrzCUbxal#2PING RUNNING pc_done=&status_id=23&speed_bpms=0&total_bytes=-1&done_bytes=0&paused_fb=1#token=B6QE9r4wbkz7f7Lovj4j

Is this normal?

The only thing that I think changed is the datto driver had some update, could that be related?

Its been indexing since I posted, Any idea?

Well … I figured I’d post how I figured it out finally …

insufficient disk space for the shadowcopy. If only I had a log entry or something that would check that before it gets stuck for week.

I dont know how to add that functionality otherwise I totally would.
