Today we updated our 3300 with 20 SIP user licenses and have begun to play with them.  Everything was going fine for a few hours, I was THIIIIIS close to letting leadership play with it as I felt more and more comfortable with it.  Then we had an implosion:

Prior to the E2T resetting (assuming that's what happened in the above log) there were pages of logs that look like these:

Do any of you guys have any idea what happened above?  
I can tell you that I was performing a test to see if my Bria Softphone (DN: 2780), installed on an iPhone and configured with multicall lines, could accept two calls (it can) and then merge them into a conference (nope).  The result was a transfer and not a conference using the softphone.  Instead of failing gracefully (if you want to call a failure that) and just not working, the 3300 looks like it was inundated with these requests resulting in the E2T crapping itself and rebooting.  Any input you guys can offer is greatly appreciated.
