TM1 Forum

Hello again to all,

A couple of times in the last two months our TM1 Admin Server crashes, overnight, which prevents any TM1 windows services from restarting.

To fix this issue we simply Restart the Actual server where the TM1 services reside. Once the server is back up and running, the TM1 Admin server is up and running as an automatic process.

When we chase the windows event logs, it confirms that an application error occured as well as telling us that it was "tm1admsrv.exe" that crashed.

It also tells us that the faulting module path was the ntdll.dll. A windows System32 dll.

Computer hope tells me that

The ntdll.dll file is a file created by Microsoft that has a description of "NT Layer DLL" and is the file that contains NT kernel functions.The ntdll.dll file is located in the c:\windows\system32 or c:\winnt\system32 directory and can also be found in the c:\i386 directory."

It also tells me that it was a security threat in 2003, but as long as the have the most recent updates (we are on Windows 2008 R2 and we do update regularly) it will be fine.

Has anybody come up against this before? Your TM1 Admin server crashing and refusing to restart until you restart the actual server?

Has anyone heard of that dll before? When it comes to TM1 or windows as a whole? Does it cause issues for anyone?

Thanks.

Trevor.

You are best to go through support who should be able to give you instructions on how to capture a dump file of the incident for analysis.

Knowing that ntdll.dll was the faulting module doesn't tell you much, a full dump file is needed to see where the fault originated.

Hello,

thanks for the reply and indeed, hopefully it will never happen again but a dump file would be more useful.

As for IBM support, the will most likely tell me what you told me lol, but if it persists I will go down that route.

Thanks.

Trevor.
