In short... No.
However the servers your connecting to likely have limits. And of course with enough sessions, you may exceed the capabilities/resources on the PAM server itself (but it takes a LOT of sessions).
But there are no hard limits in PAM that I am aware of.

Hi Support,
In PAM version 3.4.6 (AWS), do we have any limit for concurrent SSH session.
