Hello !
We're on Windows 2012 with SQL/HANA for our SAP systems.
We're running into a weird problem where sporadically the OS becomes
unresponsive.
As a result, SAP malfunctions/becomes unresponsive & we're not able to
RDP in to the server.
On hard rebooting, everything's Ok.
This is only happening to the SAP servers.
The non SAP servers in our landscape are Ok.
We're on Version 6.2 Build 9200.
When the OS freezes, SAP is still up most times...but things like
transports don't work (since OS files are inaccessible).
Also, SICK goes into the hourglass mode.
Event Viewer does not give any useful information.
Today we had an instance where our Production SCM system CI froze & we
had to reboot it.
Yesterday, it happened with our ECC Production Cluster server.
Since the sapmnt share was accessible (even though RDP was not), the
system did not go down...but in a few hours the server restarted itself
& failed over to Node 2.
We have a case open with Microsoft too...they've asked us to update the patches...but since the patches have to go in Dev-->QA & then Prod. this would take time.
We were wondering if maybe this is a known issue with a single bug fix or something else that addresses it.
Its also extremely sporadic & random...i.e. its one SAP server today & the other tomorrow...
We also have Symantec installed on all these servers.
Please help advise...
Thanks a lot !
