Switching

We have a Juniper EX4200-24 port running  JUNOS 12.3R11.2 that has been displaying this message in the log:

LIBJSNMP_SA_PARTIAL_SEND_FRAG: Attempted to send 4276 bytes, actually sent 2444 bytes

followed immediately by:

LIBJSNMP_SA_PARTIAL_SEND_REM: Queuing message remainder, 1832 bytes

Looking at this the snmp data is successfully being sent just in two chunks. The snmp data is usually between 4200 and 4500 bytes and the first send is anywhere between 2400 and 2800 bytes. The remaining data is sent in a queue. I was looking over the memory usage and I do not think that is an issue but it seems to point to that. Here is sample from the show system memory:

System memory usage distribution:
       Total memory: 1022976 Kbytes (100%)
    Reserved memory:   18464 Kbytes (  1%)
       Wired memory:  114352 Kbytes ( 11%)
      Active memory:  452016 Kbytes ( 44%)
    Inactive memory:   73264 Kbytes (  7%)
       Cache memory:  147012 Kbytes ( 14%)
        Free memory:  217160 Kbytes ( 21%)
Memory disk resident memory:  145456 Kbytes

 41698    292876(13.96)    15880(01.55) /usr/sbin/mib2d

The cpu is running around 20% so that does not seem to be the issues either. When the log message started showing this I looked at any changes being made to the EX4200 and devices along the path to the device pulling the snmp data and I am not seeing any changes. I need to double check the snmp device to see if there was a change there but so far I have not found one. Any insights on to the issue would be appreciated. Thank you.

You could try giving snmp more breathing space

try to avoid fragmentation at IP layer

set snmp max-pdu-size 8000

control the poller

set snmp throttle-threshold 80
