mismatch of inbound/outbound sessions per realm in HA pair

hi everyone!

 

I am observing a mismatch between the SDs in one HA pair.

The numbers of inbound/outbound sessions per realm are different in each SD, in some cases the
standby SD has the half of i/o sessions than the active has.

one example is the following:

ACME2# show realm
.
.
.
realm1                [In Service]
    Inbound             28   0.6     21     41     909560    147    154
    Outbound             0   0.0      0      0          0      0      0


ACME1# show realm
.
.
.
realm1                [In Service]
    Inbound             67   2.5    117     88    3203111    892    640
    Outbound             0   0.0      0      0          0      0      0


this shouldn't be a concern when a switchover takes place, right?

both SDs should be registering the same ammount of i/o sessions, or this difference is normal?

what happens with the sessions that the standby SD is not seeing?
