RSVP-TE not working

[julian]

We did an update from 15.3.3.5-patch1-3 to 15.4.1.3-patch1-9 and RSVP become unavaible.
Before this update the RSVP was working just fine.
Below are some infomartion:

Ingress LSP Name Path Name Destination Next Hop I/F UpTm Flags---------------- ---------------- --------------- ---------------- ---- --------
LSP-BKB-IIR_C PATH-IIR_C-p4 172.27.0.10 n/a 0 -EP--OIV

Tried to active the DEBUG and these messages appeared:

0x00003A01-65 (0) TPM failed to expand the hops in the hop table. return code = 0X00000002

Does somebody knows what's happening?

Thank you!

# config mpls rsvp lsp ls1 add path "pe1pe2" primary
