I've found what is probably your post on VMware Communities.

It seems there's a second 4.1 update 3 build (811144):

It fixes another panic, so trying this build may help.
PR722061: When a Linux kernel crashes, the linux kexec feature is used 
to enable booting into a special kdump kernel and gathering crash dump 
files. An SMP Linux guest configured with kexec might cause the virtual 
machine to fail with a monitor panic during this reboot. Error messages 
such as the following might be logged:

vcpu-0| CPU reset: soft (mode 2)
vcpu-0| MONITOR PANIC: vcpu-0:VMM fault 14: src=MONITOR 
rip=0xfffffffffc28c30d regs=0xfffffffffc008b50
