          This is caused by your devices failing to correctly complete an snmpwalk operation. Since we didn't create your devices and we don't run your network, this isn't really anything we can fix.

          You probably need to increase memory_limit in your CLI php.ini.

          Just for information i was getting MRTG issue @ Cacti so increased number of threads & Maximum OID's Per Get Request(
          Specified the number of OID's that can be obtained in a single SNMP Get request) to 5000 , ensure no timeout & getting all OID values in single attempt

          Regards
          Rakesh

          Is this a virtual chassis/stacked device?

          Tried changing the value from 1 to 5 but did not worked so i configured value to 5000 in config.php.

          Try increase snmp timeout(s) to 5 or 10:

          • Device page -> Properties -> SNMP -> Timeout

          or globally set (for all devices) in config.php: $config['snmp']['timeout'] = 1;

          See: http://www.observium.org/docs/config_options/#snmp-settings
