[Users] odd subset manager behavior

[Narayan Desai]

Our subnet manager started producing some weird error messages:
May 13 05:16:22 611734 [4B0C9700] 0x80 -> Errors during initialization
May 13 05:22:09 603862 [4B0C9700] 0x80 -> Errors during initialization
May 13 05:56:45 851842 [4B0C9700] 0x80 -> Errors during initialization
May 13 06:15:47 851775 [4B0C9700] 0x80 -> Errors during initialization

The subnet manager was actually up and running prior to this, and had
successfully configured the network:
May 10 14:14:19 856909 [512F9700] 0x80 -> OpenSM 3.3.15
May 10 14:14:19 872752 [512F9700] 0x80 -> Entering DISCOVERING state
May 10 14:14:20 844905 [4B0C9700] 0x80 -> Entering MASTER state
May 10 14:14:21 604958 [4B0C9700] 0x80 -> SUBNET UP
May 10 18:19:41 103790 [4B0C9700] 0x80 -> Errors during initialization
May 10 23:19:18 147739 [4B0C9700] 0x80 -> Errors during initialization
May 11 00:09:29 119760 [4B0C9700] 0x80 -> Errors during initialization

Any clue what is causing this?
thanks.
