Description (partial)

Symptom:

nv_optical_satmgr unexpectedly restarts during configuration of <CmdBold>nv satellite<noCmdBold>.

Conditions:

The configuration change must have involved removing a conflicting muxponder or transponder configuration (ie. where both a muxponder and transponder reference the same satellite slot) and also involved removing another muxponder or transponder on the same satellite.

For example, with the following starting configuration
<CmdBold>
nv satellite 100
  transponder 100g 3/0/2         # conflicts with muxponder 10x10g 3/0/2 client-slot 2
  muxponder 10x10g 3/0/2 client-slot 2  # conflicts with transponder 100g 3/0/2
  transponder 100g 6/0/2
  transponder 100g 7/0/2
<noCmdBold>

Make the following change and nv_optical_satmgr will restart.
<CmdBold>
nv satellite 100
  no muxponder 10x10g 3/0/2 client-slot 2
  no transponder 100g 6/0/2
<noCmdBold>
