IIS Worker Process (w3wp.exe) taking too much memory when TM1 Web is in use

Troubleshooting


Problem

On Windows 2008 R2, the process w3wp.exe (IIS Worker process) is taking a huge chunk of memory each time a user connects to TM1Web or opens a new sheet. On the TM1 Server side (tm1sd.exe or tm1s.exe), the RAM consumption remains stable.
