We're running ESXi-5.5.0 U3b - 3568722
We have 2 hosts that have dropped out of vCenter a couple of days ago and I've been asked to look at them. Cannot access either through the vSphere client - I get the message Connect to localhost failed: Connection failure on both. Shows some of the hallmarks of https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=20561.... I was under the impression this was fixed in 5.5 U1?
vpxa.log has entries like:
2017-04-04T06:12:21.580Z [FFA70B70 error 'SoapAdapter.HTTPService.HttpConnection'] Failed to read header on stream <io_obj p:0x1f4c6fd8, h:24, <TCP '0.0.0.0:0'>, <TCP '0.0.0.0:0'>>: N7Vmacore15SystemExceptionE(Connection reset by peer)

VMkernel.log has nothing however.
Can I do anything without a reboot to clear the buffer?
