Category: agent Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Matthias Saou (thias) Assigned to: Nobody/Anonymous (nobody) Summary: 5.4.1 segfault in ipAddressTable_container_load Initial Comment: Hi, I've just updated RHEL4 and RHEL5 servers to net-snmp 5.4.1, and have the exact same problem as described here on a few of them : http://sourceforge.net/mailarchive/forum.php?thread_name=46C1A8D9.7040607%40softax.pl&forum_name=net-snmp-coders I was previously running 5.4 fine, but it was spitting many useless messages to syslog, which 5.4.1 fixes on the servers where I tested it. What the problematic servers have in common are "duplicate addresses" : They either have VPN connections established (which are P-t-P with the same address on the local side), or are Xen hosts with many vif and veth interfaces. The other thing that strikes me is that no 64bit servers seem affected, only some 32bit ones. The segfault happens almost immediately after boot. All I get in /var/log/messages is : Sep 14 10:24:20 polar snmpd[31612]: netsnmp_assert !"registration != duplicate" failed agent_registry.c:535 netsnmp_subtree_load() Sep 14 10:24:20 polar last message repeated 2 times Sep 14 10:24:20 polar snmpd[31612]: Duplicate IP address detected, some interfaces may not be visible in IP-MIB Sep 14 10:24:20 polar snmpd[31612]: Duplicate IP address detected, some interfaces may not be visible in IP-MIB Backtrace : (gdb) bt #0 ipAddressTable_container_load (container=0x9907708) at ip-mib/ipAddressTable/ipAddressTable_data_access.c:347 #1 0x0016779d in ipAddressTable_container_init (container_ptr_ptr=0x24c5e0, cache=0x9906ec8) at ip-mib/ipAddressTable/ipAddressTable_data_access.c:137 #2 0x00162e9e in _ipAddressTable_initialize_interface (reg_ptr=0x0, flags=0) at ip-mib/ipAddressTable/ipAddressTable_interface.c:2003 #3 0x0014aceb in initialize_table_ipAddressTable () at ip-mib/ipAddressTable/ipAddressTable.c:104 #4 0x0014ad7a in init_ipAddressTable () at ip-mib/ipAddressTable/ipAddressTable.c:56 #5 0x001fd09a in init_mib_modules () at ../agent/mibgroup/mib_module_inits.h:20 #6 0x004290ef in main (argc=8, argv=0xbf969454) at snmpd.c:901 Please let me know if more information could be useful. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=112694&aid=1794532&group_id=12694 |
