EAP 107.130 constantly raising 2-3 IDE errors

Dmitry et al, I think there is some regression in EAP 107.130 as I get 2-3 IDE errors constantly. This is an environment that 107.130 upgraded from the previous EAP 107.40. The errors will pop up when doing nothing and trigger every few seconds. I had to invalidate all the caches and restart in order to make it work without constantly raising these errors. You might want to double check the upgrade path, some remnant remains that causes this. I submitted them via the feedback tool as well, just figured to give some more feedback.
