tNet0 task has been terminated after [REDAWorker_leaveExclusiveArea ()]

Platform : mpc8548 (p2020 smp), vxWorks 6.9.4.0

RTI-Connext ver : 5.2.0

Hello.

When I reboot  my system, a ppc machine has been crashed sometimes.(not always, most times it worked after reboot)

It has been unable to analyze because network connection also stopped.  So I just rebooted the system.

This time with H/W part support,  I finally got serial i/o and saw some errors (edrShow result) below.

This says "RTP < bin/WEPSIF_TPD.vxe (0x13bbd670)" is crashed

while "0x8cb11a50 REDACursor_finish+0x68 : REDAWorker_leaveExclusiveArea ()" is running.

And after that tNet0 stopped.

This is a RTP application and I beleived RTP application cannot mass up with kernel process such as "tNet0".

I wonder which scenario could cause this phenomenon.
