Does the "Generate Session ID" operator have an upper value limit?

Hi everyone,

I'm using the "Generate Session ID" operator from the operator toolbox in one of my processes. As date attribute for this operator I use a boolean attribute, which indicates the start of a session. However, when I tried to run this process on a large dataset,  where my boolean attribute has more than 3000 "true" examples, I notice that the Session ID stops increasing at 2999.
Is this a limit that is set in the  operator? And if yes, is there a way to remove this limit?

Thanks a lot!
