CDS systems working well, just some minor creaks

No major issues since Tuesday's Dolphin driver upgrade. I did notice three things happened Wednesday evening between the hours of 19:00 and 20:25 PST: h1iopseih23 and h1iopseih45 had long'ish cpu times (13uS) just over an hour apart, and 20 minutes later some CRC errors appeared on h1seib3.

This afternoon I cleared the CRC and ran a full DIAG_RESET, soon after h1iopseih16 SWWD IPC receiver saw 5 errors in one second. As far as I am aware, this is the first time LHO has seen a transient SWWD IOP receive error, which has been seen at LLO previously. I'm not sure if its a coincidence that it appeared some seconds after the CRC/DIAG resets.
