This article describes the "ifext_uspipc_connect_and_send_to_pfe: send to pfe <number> failed" error in the syslog, and explains how to resolve it.

An example of the error is below:

nsd 1444 - - ifext_uspipc_connect_and_send_to_pfe: connect to pfe 34603009 failed
nsd 1444 - - ifext_uspipc_get_flow_stats: Could not get stats from pfe 34603009

This log is related to the internal traffic polling statistic: The socket channel resource is not ready.

The socket could be busy because of a high volume of SNMP polling/pushing, which can trigger the system to intermittently generate an internal message .

Check the SRX to see if it is configured with a high volume of SNMP polls/traps.

If the SRX is configured with a high volume of SNMP polls/traps, reduce the number of polls/traps and check the result.

If there is no SNMP poll/trap when you see this log, collect the information below and contact JTAC.
