TM1 Forum

We are seeing an odd issue on our 10.1.1 platform.

Certain processes are running in duplicate, triplicate, or even quadruplicate with only one request. The issues occurs when processes are run from an action button on a websheet or the administration section of TM1 Web. The issues does not persist when running from Architect or Perspectives.

We have put debug logging on to see if there is any contention or rollbacks happening; there doesn't seem to be any need for TM1 to re-run the process. The issue only occurs when using CAM security. Flipping to native security, the issues goes away.

Has anyone seen anything like this?

Don't get me started on the abomination that is CAM security.

Got some clarity on the issue and it actually is caused by configurations on our load balancing appliance (F5). The F5 has a TCP timeout of 5 minutes and if an HTTP request (the Action button call to the TI process), the F5 actually causes it to re-post. Working with the LB admins to change this to match the TM1 web http execution timeout setting.
