UiPath Studio 2022.10.4 huge RAM usage

Help Studio
1

Hello,
premise: we had the UiPath Studio 2021.10.4 installed on a Windows 2016 Server with 8Gb Ram (enterprise license, user-mode installation)
After i’ve checked the hardware requirements for Studio 2022.104, i’ve choose to install it on my local computer, which have 16gb RAM

Now, i’ve converted some UiPath process from 2021.10.4 to 2022.10.4, trying to compile & publish to orchestrator. The memory usage runs over 9gb!!

Furthermore, when i’ve other applications opened, such a chrome sessions, outlook etc… the deploying of the UiPath crashes

from UiPath.Studio.Project.log:
"=> [ERROR] [UiPath.Studio.Project] [50] System.OutOfMemoryException: Insufficient memory to continue the execution of the program.

Is it possible to reduce memory consumption?

Hello @dBeo,

I believe the issue w.r.t project validation\publishing is improved in later versions like 23.4.x and 23.10.x (i.e greater than 22.10.4 version that you are using currently) as quoted below:

From 23.4.0 UiPath Studio release notes

From 23.4.2 UiPath Studio release notes

From 23.10.0 UiPath Studio release notes

From 23.10.4 UiPath Studio release notes (latest enterprise version as of today)

Suggestion:
If possible\feasible, Please upgrade your UiPath Studio to 23.10.4 (latest) version and see if this helps overcoming the problem that you are facing.

On a side note, there were similar issues reported in the past and based on those reports, these improvements are made.

Hello @Dominic

Thank you for the feedback

I’ve installed the v2023.10.4.
From a point of view of RAM Usage, the performance are better.

but, now, while publishing the (same-above) project, sometimes i got a Timeout.
UiPath.Studio.Log: “[ERROR] [UiPath.Studio] [16] Error: Publish of Process project to Orchestrator failed. The operation has timed out.”

However, the issues reported in following post UiPath throws Bad IL Request when its compiling the activities are still present in v2023.10.4, and I’ve libraries which use the SqlClient functionalities

I’ll rollback the studio to v2021.10.4, waiting a fix for the SqlClient issue

Hello @dBeo,

Thanks for the update. Regarding the error mentioned in the forum link you shared above, can you please try the suggestions listed in the docs and see if it helps? Also, when does this issue occur during publish, or runtime execution?

Hello Dominic

I’ve created a sample in Studio v2023.10.4, with UiPath.Database.Activities 1.7.1:

RunQuery activity with “Micorsoft.Data.SqlClient”:

While compiling in Studio, the “Bad IL format” exception is throw but the activity runs without further issues

From UiPath.Studio.log:
"[WARN] [UiPath.Studio] [1] GetCompilableWorkflows: allWfCount = 5, normalizedDistinctWfCount = 4
*[ERROR] [UiPath.Studio.App.Logging.OutputLogger] [119] Bad IL format. *

  •   The format of the file '..\.nuget\packages\uipath.database.activities\1.7.1\lib/net5.0-windows7.0/runtimes/win-x64/native/Microsoft.Data.SqlClient.SNI.dll' is invalid. *

  •   ..\.nuget\packages\uipath.database.activities\1.7.1\lib/net5.0-windows7.0/runtimes/win-x64/native/Microsoft.Data.SqlClient.SNI.dll*"

Executing on UnAttended Robot, the UiPath.Executor.exe crash

Hello @dBeo

If the activity works fine but still the UiPath.Executor.exe crashes, then the problem could be with something else (I may be wrong). It’s better if you could replicate the issue and generate and share the UiPath Diagnostic Tool logs

If it’s timing out, you probably have a folder with tons of files in it, like screenshots. You shouldn’t store anything in the project folder that doesn’t need to be published.
