BFD session not coming up

[rajesh_alef]

Product Name: HP 5900AF-48G-4XG-2QSFP

HP Comware Software, Version 7.1.035, Release 2208P01

I have a L3 switch HP 5900AF-48G-4XG-2QSFP+ Switch with 2 Processors, Configured with BFD with OSPF using 2 Ten Gig interface with multiple vlans per interface.

Via one link OSPF and all BFD sessions are forming properly i.e. total 32 BFD sessions are forming through this Link.

But on other link OSPF neighbor forming properly and loading to FULL state, but BFD sessions are not at all forming

Some sample logs are attached here:--
