Creatio Instance very slow/Not working

Sub: Creatio Instance very slow/Not working


We have installed Creatio version 8.1.2 version with MSSQL DB in virtual machine, but once logged into 3 or 4 users at a time the instance is not working. Could you please help on this.


After restart the Redis and Application Pool it is working as expected.

It would be better to contact Creatio support regarding this issue.
Or double-check that you installed the application correctly…

Hi Dmytro,

Okay, could you please share your inputs on this apart from above comments.

Bala Koteswarareddy,




Please take a look at this article


In fact, IIS on different OS supports different numbers of concurrent connections, resulting in the fact that when the limit is reached, new requests won't be processed, the UI that sends these requests will not respond, and the Creatio Instance will be very slow/not working.

This is the only possible explanation of why this issue occurs.

@Oleg Drobina,


Thank you for your inputs.
