hello

I use the following configuration, to monitor switchs
<Plugin snmp>

   <Data "uptime">
     Type "uptime"
     Table false
     Instance ""
     Scale 0.01
     Values  "DISMAN-EVENT-MIB::sysUpTimeInstance"
   </Data>

   <Data "memory_free">
     Type "memory_free"
     Table true
     Instance "CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolName"
     Values  "CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolFree"
   </Data>

   <Data "memory_used">
     Type "memory_used"
     Table true
     Instance "CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolName"
     Values "CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolUsed"
   </Data>

   <Data "CPU_usage">
     Type "percent"
     Table false
     Instance "cpmCPUTotalMonIntervalValue"
     Values "CISCO-PROCESS-MIB::cpmCPUTotalMonIntervalValue.1"
   </Data>

   <Data "std_traffic">
     Type "if_octets"
     Table true
     Instance "IF-MIB::ifDescr"
     Values "IF-MIB::ifInOctets" "IF-MIB::ifOutOctets"
   </Data>

the issue is it only support 3 devices, once I add 4th one i get
kernel: collectd[57903]: segfault at 18 ip 000000363b075fb3 sp 
00007f4416b6d580 error 4 in libc-2.12.so
and
snmp plugin: host somehost snmp_sess_synch_response failed: Timeout

I think it is a limitation from the OS (centos6) but can't find where,

any ideas plz ?
