Joining of two Datatables "Bot become not responding"


I have the same issue “Bot become not responding”. In my case, there are two datatables(for e.g. DT1 & DT2). In DT1, there are almost 56000 rows and in DT2, 110000 rows. I have joined these two datatables (DT1 & DT2) using “Join Data Tables” activity to produce records which are common in both the datatables (DT1 & DT2) but just after the execution of workflow robot “become not responding”.

Please provide me the root cause of this issue and the solution to resolve this issue.


Hi @nidheessingh,
Are you able to provide any logs? Event Viewer etc. You could also check if ram or PageFile is not overloaded during that huge operation.

Hi @nidheessingh
Welcome to uipath community
may i know at which activity or after which activity this error occurs buddy
you can check that by running in debug mode
kindly check that and let know @nidheessingh

Looks have to increase memory.
Can you provide your system details. Where bit installed

Hi @Palaniyappan,

Robot hangs and not responding when control comes onto Join Data Tables activity.
