WF Studio Not Responding During Loops (memory max out)


I’ve been having issues lately with ram maxing out (running on a machine with 16 GB of ram) and studio not responding during for each loops (100+ elements). These loops also contain while loops and if-else condition actions. These loops aren’t extremely complicated - it’s essentially a vlookup cross-referencing two different tables. Are there any tricks to cut down on memory usage during loops or vlookup custom actions that anyone has had success with?

It seems crazy that it’s maxing out memory usage. I’ve already increased the Xmx to 4096m in the workfusion-studio.ini fyi.

Any help with this is appreciated, thank you!

Hi Wilson, can you send these RPA Express logs:

  • RPA logs from C:\RPAExpress\RPA\logs
  • Studio logs from C:\RPAExpress\Studio\logs
  • hs_err_pid.log file from C:\RPAExpress\Studio, if you have any?

Thank you

Sorry for the delay on this, (2.9 MB)


Hello Wilson.

I investigated your logs, but cannot find anything regarding memory exceptions. But seems you missed several files. Could you please also attach studio.log and rpa-hub for the 17-July?
Thank you in advance.

Hello @wwylie.
Is this still actual? If yes, we need additional information to investigate from our side.

Hey @Lera sorry I must have missed your last post. I’ll be sure to let you know if I see the issue again. Thanks!
