I could trace the issue to ConsistencyInvoker, it is called every 15 min from a cron job and each time it runs, omiagent crash with a segfault.

I have opened an issue in the DSC repo as well (microsoft/PowerShell-DSC-for-Linux#601)

[JumpingYang001]

@johanburati could you file an ICM and attach the core file in ICM and assign it to omi team?
BTW, what is your Operating System version?
It is not dsc issue, dsc don't use omi after 1.1.1 versoin, so you can close dsc issue.

[johanburati]

@JumpingYang001, I have already created a ICM on 2019-07-23 with a link to the core files,
it was assigned to the Omi team and you already commented on it, but there is no update since.

I would appreciate if someone could follow up on it, let me know if you need me to send you the number.

[JumpingYang001]

@johanburati yes, I need the ICM number, thanks.

For reference it was a dsc issue, the DSC extension installs version 1.1.1-294 of the dsc package, this version cause omiagent to segfault, installing version 1.1.1-926 manually fix the issue.

I have submitted a fix for the extension Azure/azure-linux-extensions#877

[JumpingYang001]

Since it is not omi issue, I close this issue, thanks.

[johanburati]

If you are having this issue check Azure/azure-linux-extensions#875 for details and solution.
