Problem Description

Issue

The entirety of AMP restarts every 2-3 days.
I have created a post in Discord but haven’t heard back yet.
Since I have the Advanced license, I thought: Lets make a support ticket :wink:

Reproduction Steps

  • Have applications running
  • Leave them running
  • Wait for it to random restart every few days

Additional info from the Discord post:

My AMP randomly restarts

Last few rows on the log file:

[05:55:00] [System Info/16]       : Updating remote source CubeCoders/AMPTemplates:main
[05:55:00] [System Info/16]       : Updating existing remote source https://github.com/CubeCoders/AMPTemplates.git...
No stash entries found.
[06:11:00] [System Info/29]       : Updating remote source CubeCoders/AMPTemplates:main
[06:11:00] [System Info/29]       : Updating existing remote source https://github.com/CubeCoders/AMPTemplates.git...
No stash entries found.

After that, nothing in the logs.
10 minutes later, all instances suddenly restarted including the applications it runs.
This happens about every 2-3 days.
It has been doing this since about AMP 2.6 but never bothered me enough before now

Check the logs of the individual instance, the logs you’ve shared are from ADS rather than the individual instance.

Hi Mike,

Yes, when these restarts happen, it restarts all instances including ADS.
This is also visible because it starts a new ADS log file afterwards.

Have you checked dmesg to see if the kernel is killing processes?

Hi Mike,

I think I have found the issue.
Ubuntu and Debian run a apt-daily-upgrade.timer which restarts many services including AMP.
It then requests soft-stops on all instances and shuts down ADS gracefully, which is why there are no errors present.

Since I prefer doing weekly patchrounds myself I have disabled this timer in systemctl and hope that fixes it for now…

Following is visible in the logs:

```sh
Selecting previously unselected package ampinstmgr.
Preparing to unpack …/4-ampinstmgr_2.8_amd64.deb …
Unpacking ampinstmgr (2.8) …
Setting up ampinstmgr (2.8) …
