Slow disk and retransmissions after OneAgent update

[Zimmer]

Hello,
Does anyone has this kind of behavior, when OneAgent updated to Version 1.253.245 almost all servers' Slow Disk alarm appeared, from the graph, it wasn't very critical at all, IO increased a bit, and also it didn't affect service at all. After some time we realized that there is also a lot of retransmission packets. We decided to roll back and reinstall the previous version of OneAgent Version 1.251 and boom! all problems solved.
Is there any way to identify somehow the root cause? and where to find logs in dynatrace if the log from the menu doesn't shows anything, there should be some logging of OneAgent from the host itself maybe?

If you had this kind of experience before, please share the steps.
Thanks.

Hi, it's no my case, but do you see this in Win and Linux? I suggest also to open a support ticket with this to help you dig a little deeper.
