[j-nsp] high CPU usage of RPD process

[Martin T]

RPD process(/usr/sbin/rpd -N) has a high ~80-90% CPU usage:

  PID USERNAME     THR PRI NICE   SIZE    RES STATE    TIME   WCPU COMMAND
 1278 root           1 122    0   552M   538M RUN    215.0H 86.13% rpd

..on M10i platform(RE-850) without an obvious reason- there has been
no changes in network topology, all the interfaces are up, no
configuration changes has been done. There isn't anything useful in
the "show log messages" output. If I check the updates sent by BGP
peers, there is not excessive flood by none of the peers. Anyone seen
such behavior before where RPD has high CPU utilization without a
clear reason? Is it somehow possible to trace the updates going to RPD
in order to understand better, what exactly RDP is doing at the time
when the CPU utilization is high?
