outofMemory Exception TM1 9.5.2 64bit

[krishnadixit]

Recently We upgraded our RAM & Number of cores on our server. Initially we had 32GB RAM & 2 Processors on our Prod server. Since we did not wanted to disturb existing environment we setup a new server machine with following configuration:

Windows 2008 R2 Enterprise SP1
2 Processors - 6 Cores
48GB RAM
64-bit os
TM1 9.5.2 64 bit
Drives:
a. C: 58GB free & pagefile.sys 1GB
b. E: 29GB free & pagefile.sys 71GB (since we wanted to keep C drive free we created a big pagefile on E: drive, which is our swap drive)
c. F: 140GB free & no pagefile.sys. Our TM1 installation is in this drive.

The existing (old) environment has just 2 processors - 2 cores & just 32GB RAM installed. It has 15GB pagefile.sys in E: Drive (Swap drive)

Now when I started TM1 data server on new machine the server crashed displaying 'outofMemory' exception. The log file says:.

I am surprised to see 'Not enough storage is available to process this command' error. The server starts & loads on existing old server normally & is working fine.

Any ideas or suggestions?

Have you checked on the old box to see how much physical and page memory is being used? Have you checked memory usage on start up on the new machine? How big is your page file on the new machine?

[tomok]

You still have to have a paging file equal to the amount of RAM, even if you will likely never use it.

@Jim & @tomok
Thanks for your suggestions. The Old box has 32GB RAM & 15GB Page memory. The memory usage on new box without tm1 startup is just 3GB out of 48GB & has page memory of 1GB & 71GB on C & E drives respectively.

Any idea?

Maybe you have installed the 32 bit version of the instance on the new 64 bit box which (I think) would limit you to 4GB?

(I can't really remember if the above is possible but it seems to ring a bell....)

Cheers,

It is possible, and would certainly account for this error as there would be 32 bit address space fragmentation to contend with. See here.

In Task Manager the TM1S process would have *32 next to its name if this were the case.

@Duncan & Steve,

Thank you. You were correct, I'd installed 32bit version. My bad
Now installed 64bit & is working. Thanks for the solution. I appreciate it.
