hey all,

curious if anyone has seen this and knows why it happens or if its anything to 
be concerned about.  we received new MX480s with the new 64G Routing Engines 
where Junos is in a VM, and on both MX480s we have seen messages like the 
following:

MX480-2-re0> show system alarms 
2 alarms currently active
Alarm time               Class  Description

2016-11-28 21:25:02 UTC  Minor  RE 0 Mismatch in total memory detected

with syslog messages like this:

going to open a TAC ticket, but was curious if anyone else had seen this and 
had any insight.

Thanks,
