After upgrading from ESXi 5.5 Update 2 to Update 3, deleting snapshot randomly crashed virtual machines. Updating VMware tools didn't help. No crashing problems before with snapshots on the same server for the last ~3 years. Problem started with Update 3.
So far, this has happened with Windows XP, 2003, 2008R2 OS with updated VMware Tools.
Here is an example of one of the systems that just crashed right after a snapshot delete:
