OneAgent pod in crashLoopBackOff

skatshell — Wed, 17 Dec 2025 12:54:13 GMT

I upgraded the version of oneagent to latest from 1.277.196-raw. Since then one agent is crashing with these lines of log. What can I do to resolve the issue?

@skatshell which OS are you using on EKS? if I had to guess 'bottlerocket'?
Also are you deploying as full stack or App Only?
Implementation on a read only system will vary, however you would typically set the 'readonly' feature flag to true where a read only environment is present to allow for the install (below)
