RE: snmpd stops responding after ~ 1000 snmpwalks

There is more:

(gdb) list
985 receive();
986 #include "mib_module_shutdown.h"
987 DEBUGMSGTL(("snmpd/main", "sending shutdown trap\n"));
988 SnmpTrapNodeDown();
989 DEBUGMSGTL(("snmpd/main", "Bye...\n"));
990 snmp_shutdown("snmpd");
991 #ifdef SHUTDOWN_AGENT_CLEANLY /* broken code */
992 /* these attempt to free all known memory, but result in double
frees */
993 shutdown_master_agent();
994 shutdown_agent();

You should run it in a debugger or attach a debugger to it and see

gdb -p PROCCESSID
