failed to send TCLO outgoing ping

[Brook55]

Hello I'm getting this error on three OpenBSD machines that were initiall set up as "other 64bit" OS's under ESXi 4.X. After the upgrade to ESXi 5.0 the error started occuring:

vmware: sending length failed, eax=00000000, ecx=00000000

vmt0: failed to send TCLO outgoing ping

Any ideas on what could be causing this?

Thanks in advance!

issue appears to be with the vmt driver in openbsd and not an ESXi issue. The devlopers of the driver have not yet upgraded to esxi 5 but will and will probbaly have a fix in the near future

this post shows the steps on how to remove the driver which should eliminate the error
