When troubleshooting a VMotion problem on an unpatched ESX 3.0.2 update 1 host today I wanted to use vmkping. This constantly resulted in the following error message:
syscall version mismatch (compiled: 0x7616c4e3, kernel: 0x50f63116)
I did not find any useful info on google so I checked the VMware knowledge base, maybe some over at VMware can read my mind or it’s a pure coincidence they just updated the following KB article, it seems to be a bug which is fixed in ESX-1002424. It’s actually mentioned in the release notes… I should read those more often I guess.
