My previous claim was incorrect -- net-snmp DOES NOT suffer from the problem documented in this PR. The code in net-snmp which uses kvm_getprocs(3) is for the hrSW*Run OIDs, which (properly) uses KERN_PROC_ALL to ensure they count kernel threads for kernel modules. The hrSystemProcesses OID with net-snmp returns the correct number of system processes (not including threads). Verification: icarus# snmpwalk -v2c -c public localhost hrSystemProcesses HOST-RESOURCES-MIB::hrSystemProcesses.0 = Gauge32: 60 So this PR/issue is specific to bsnmpd. Sorry to waste your time, Sylvio! The PR should remain open as bsnmpd needs to be fixed. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, US | | Making life hard for others since 1977.
