ARRIVAL DATE 2010-11-17 13:47:29

CLOSE DATE 2010-12-21 10:31:39
RELEASE NOTE On MX routers running Junos 10.2 and above, under certain
conditions it is possible for command 'show interface statistics' to get stuck
(i.e. not return anything and hung); 'show pfe statistics traffic' to return
"error: the mib-process subsystem is not responding to management requests" and
SNMP queries failing. If this issue is encountered, a restart of the pfed
process recovers from the error. Restart PFED via root shell ps -A | grep pfed
| egrep -v grep | awk '{print $1}' | xargs kill Only if running 10.2S4, where
in pfed tracing got enabled by mistake, execute the below to disable pfed
tracing. ps -A | grep pfed | egrep -v grep | awk '{print $1}' | xargs kill
-INFO Note the kill -INFO results in a toggle action - if pfed tracing is OFF,
it is truned ON and if it is enabled it is turned OFF.
Thanks & Regards
Tarique Abbas Nalkhande

Hi
We encountered this issue in 10.2R3 (fixed in 10.2S6.3). Mib2d and PFED become
stuck due to a bug (PR). You need to restart the pfed process (it manages PFE
stats : no issue if you restart it).
Kill, via the shell, the PFEd process (there is no restart via cli). it will
restart then.
Regards,
David

In many cases like these, we've had to restart chassisd
(chassis-control). This is service-impacting.
