Several times in the last couple weeks, I've had a system reset. The most recent at 5:09AM. The error log shows:

5:09AM, while running "Phone", MemoryMgr.c, Line:3635, NULL handle

Seems strange that this would occur in the middle of the night for no unknown reason. I noted that there have been a couple other instances of this fault posted in the forum, but no discussions about what might cause this or possible solutions.

Anyone else with this issue?
