Oneagent crashing with Unrecognized parameter: PROCESSHOOKING=0

[Fabian-K]

Hi,

we are facing the following issue for the oneagent pods after updating from 0.8.2 to 0.9.4. I´m not sure why this happens, also rolling back to 0.8.2 shows the same issue. Do you have a suggestion where to look at?

Thanks!

Hello @Fabian-K - which OneAgent version are you using?

[Fabian-K]

Thanks for the quick reply! The OneAgent CR shows 1.209.169.20210219-191956 in the status

[lrgar]

I believe you are using a very old OneAgent image version, could you please update to the latest? It's configured on the .spec.image field from the OneAgent object.

You are right, thanks! I was running image digest sha256:a48e2da2d2e76575176f71acc89fe9774d3f4f732b8aa9f47aadf19949e4a1f5, no idea how old that is/was. dynatrace/oneagent:1.48.1000 is working fine.
