reslck.timeout = 600

Oct 24 10:12:06: vcpu-0| [msg.scsi.reservation.locktimeoutrecover] This virtual machine has been unresponsive for more than 20 seconds and has caused another virtual machine sharing a disk with it via SCSI reservations to believe it has died. It is therefore unsafe for this virtual machine to resume activity, and this virtual machine will now terminate. If a 20 second delay is not long enough to be an accurate 'death heuristic' it can be changed by setting the "reslck.timeout" configuration variable. It is extremely unlikely that this should ever be necessary.
