I am meditating on the OAF, and had it running and calculating things.  I had the outputs disabled so I could take reference traces in DTT, but the Adapt block was calculating for MCL.  At some point, all the numbers froze, and the CPU meter had gone up to ~256ms.  Usually it's around ~70 or so for the configuration I had (2 witness sensors and one degree of freedom enabled....no c-code calculations on any other signals).  The "alive" heartbeat was also frozen.

I ssh'ed into c1lsc, ran ./startc1oaf in the scripts directory, and it came back just fine.

Anyhow, I don't know why it got funny, but I wanted to record the event for posterity.  I'm back to OAFing now.
