Hi,
We have a new Dell R820 running Server 2012 Std as a Hyper V host, with 6 Server 2008 R2 Std VMs. 2 of the VM's are RDS servers, one with 25 users (RDS1) and the other with 10 users (RDS2). Since go live approx 3 weeks ago, the 2 RDS VM's have been crashing. RDS1 approx once a week and RDS2 approx 2or 3 times a week. Some crashes will leave a dump file, other crashes will not. From initial look at the dumpfiles, I have the following info:
PAGE_FAULT_IN_NONPAGED_AREA (50)
Invalid system memory was referenced. This cannot be protected by try-except,
it must be protected by a Probe. Typically the address is just plain bad or it
is pointing at freed memory.
Arguments:
Arg1: fffff680003b9268, memory referenced.
Arg2: 0000000000000000, value 0 = read operation, 1 = write operation.
Arg3: fffff800016f2dbc, If non-zero, the instruction address which referenced the bad memory
address.
Arg4: 0000000000000002, (reserved)
They have referenced aAcentral.exe (a program from our Practice Management software APS), chrome.exe twice, and iexplore.exe.
None of the other VM's (2008 DC, file/print, mailserver, sql server) are crashing, just the 2 RDS VM's, which restart themselves, then users log back in, obiously losing any work they had open.
Can anyone help me out as to the cause and how to stop it?
