Test is running continuous network send/receive operations. Only Basestation (dvt1) and one prototype (TIB4) are running. FSM fails when it tries EV_INVALID_SYNC(4) event while in ST_RX_ON(6) state.

Here's the exception:

Breakpoint 1, PanicP__Panic__panic (pcode=0x1c, where=0x51, arg0=arg0@entry=0x4, arg1=arg1@entry=0x6, arg2=arg2@entry=0x0, arg3=arg3@entry=0x0) at /home/vagrant/data/tag_integration/mm/tos/system/panic/PanicP.nc:755
