Bind suffered from a crash on one of our caching servers, a core dumb for named was generated.
We are running BIND 9.7.1-P2, on rhel 5.5, kernel 2.6.18-194.el5. The only useful log lines found at the crash time are from "general.log", following are the lines: 27-Aug-2010 16:43:04.901 query.c:1784: INSIST(! dns_rdataset_isassociated(sigrdataset)) failed, back trace 27-Aug-2010 16:43:04.907 #0 0x41128b in assertion_failed()+0x4b 27-Aug-2010 16:43:04.907 #1 0x552e6a in isc_assertion_failed()+0xa 27-Aug-2010 16:43:04.907 #2 0x4180d1 in query_addadditional2()+0x1181 27-Aug-2010 16:43:04.907 #3 0x4b64df in dns_rdata_additionaldata()+0x12f 27-Aug-2010 16:43:04.907 #4 0x4e3a9b in dns_rdataset_additionaldata()+0xdb 27-Aug-2010 16:43:04.907 #5 0x414c73 in query_addrrset()+0x253 27-Aug-2010 16:43:04.907 #6 0x418ef5 in query_find()+0xdd5 27-Aug-2010 16:43:04.907 #7 0x41c23b in query_resume()+0x1fb 27-Aug-2010 16:43:04.907 #8 0x56cfcc in run()+0x1dc 27-Aug-2010 16:43:04.907 #9 0x3951a0673d in _fini()+0x3951486f75 27-Aug-2010 16:43:04.913 #10 0x39512d3d1d in _fini()+0x3950d54555 27-Aug-2010 16:43:04.913 exiting (due to assertion failure) Any advice on this fault ? Thanks in advance
