First recording dropped by second request

Hi all,
Consider the following scenario:
u1-u4 are in session an u1 being moderator starts recording.
u2-u3 are in a different session,
Whenever u2(moderator) starts recording, recording of u1-u4 automatically gets dropped, where I’m getting following at frontend:

 sessionID:"gbfmowkfvkhwdhue", status: "off", error: "busy"

and recording between u2-u3 gets started.

There is only one jibri, with jitsi-meet server.
Looks like jicofo is not blocking the 2nd request by saying jibri is busy.

Wondering what could be the problem. Please help.

Can you attach the Jicofo and Jibri logs?
