These are generated in repeated intervals in the /var/log/vmkernel.log only when I do large SCP transfers of our VM-images from within an Esxcli Shell with SCP or SFTP. About 5-10 minutes into the transfer the Esxi server hangs and has to be Hard Reset. I have thus been unable to do any transfers of our vm-images to a backup server. I have even tried when the server is in maintenance mode.
Our dedicated EX4s server (with LSI MegaRaid controller) is with Hetzner.de and is thus not in the Vmware HCL - Hetzner have only indciated that their EX servers are compatible with Esxi5.1.
Are there any SR requests for the same errors or similiar issues?
