Fixed In Version: 3.6.5-1
Doc Type: Bug Fix
Doc Text:
Previously when the RHEVM Guest Agent was running and had some IO errors on reading from or writing to the VirtIO Socket errors would lead to a non ratelimited endless loop until the error would resolve itself. This had a very bad performance impact on the Virtual Machine. This has been resolved.

Comment 1 Jiri Belka 2016-04-19 12:09:03 UTC 
ok, RHEV-Agent64.msi - 4.13.4 (as there's no WGT iso build yet containing newer agent)

a defensive code was added to the agent that adds log message visibile in DEBUG level informing about I/O issue with virtio-channel and sleeps 1s. verified with stopped vdsm on hosts.
Comment 4 Michal Skrivanek 2016-05-06 21:30:22 UTC 
Will be shipped in 3.6.6 guest tools
Comment 5 Jiri Belka 2016-05-16 10:27:23 UTC 
ok, 3.6-6 wgt iso
