C8-Pro hub locking up during backup

C8-Pro.

First lockup was after updating to 2.3.8.128.

Two total lockups on 2.3.8.128.

Upgraded to 2.3.8.134. One lockup so far.

Hub is completely locked up other than recovery UI: :8081 is accessible. Nothing runs. Completely unresponsive.

Happens every time at 03:01 on the dot, which is when the nightly backup is scheduled. Last log entry is a few seconds after 03:01. Then nothing in logs until hub is restarted.

No lockups at any other time. Only at 03:01. Seeing as this time messes up my morning sunrise lightly routines causing people to oversleep, I'm changing it to mid-day.

Cloud backups ARE present, so it seems to complete the backup and upload it, but hub locks up completely during/immediately after backup.

It will help if you PM your hub UID to @gopher.ny and @bcopeland so they can look into your and engineering logs.

This doesn't sound like it's back-up related, but to rule that out, could you please send me a private message along with your hub id so we can check its engineering logs?

Multiple times, right at backup time? A whole lot of nothing else going on at 03:01. Canโ€™t imagine how itโ€™s not backup related. Sending UID.

Thanks for the PM. Is your hub accessible now? Because the backup ran successfully and the hub has not been rebooted after the task was completed.

Yeah itโ€™s up. I rebooted it this morning after it was locked up again. Itโ€™s not every backup, either. Been 3 total in the last week. All right at 03:01, one this morning at that time.

Any update on this?

Another lockup today:

Last message in logs was at 10:05, which is when I have backups scheduled now:

Previous hub was locking up at 03:01, which is exactly the time I had the backups scheduled for. Changed it so it didn't lock up in the middle of the night on me, so now it's set for 10:05AM and that's when it locked up again.

This is, 110% for sure, caused by the backup somehow. There's just no way it happened a few times at 03:01 and now at 10:05, which are the times I had set for backups, and I've had no lock ups at any other point in time.

Latest lockup on version 2.3.8.134:

I have given up doing auto backups ..
Always had memory leaks or other stuff happen when turned on.
I just do a backup when I make a lot of changes then do a reboot.
this seems to work best for me < have not had a problem since doing this.
I get that this is a stop gap way of doing things, but it works..

Update your hub, the recent release upgraded the database engine. Long story short they think it will fix a lot of the random lockups people were having recently.
