[j-nsp] RPD Crash on M320

[Alireza Soltanian]

Hi everybody

Recently, we had continuous link flap between our M320 and remote sites. We
have a lot of L2Circuits between these sites on our M320. At one point we
had crash on RPD process which lead to following log. I must mention the
link flap started at 12:10AM and it was continued until 2:30AM. But Crash
was occurred at 12:30AM.

The case is we always have this kind of log (except the Crash) on the
device. Is there any clue why RPD process crashed? I don't have access to
JTAC so I cannot analyze the dump.

The JunOS version is : 11.2R2.4

 

Thank you for your help and support
