Description (partial)

ifmgr process continuously crashes on active DRP card after breaking circuit(even PEM OIR) for A2 and B2 PEM

After doing A2 and B2 PEM OIR/circuit break on FQ by which RP FO and staby DRP reload is triggered, ifmgr is crashing continuously on active DRP card which is in diff power zone.

1) Trigger: A2 and B2 PEM OIR.(PEM removal/ciruit break)
2) Setup needed: FQ system with 2 RPs and one DRP pair where DRPs are spanned such that stby DRP is in the power zone which loses power on this PEM OIR and active DRP on the power zone which does not lose power on this PEM OIR. Likewise, active RP should be placed on the powerzone which loses power, so that RPFO will be triggered.
