Abort in dig after zone transfer
In the mood for bug reporting now ... :-) Sometimes dig gets into some sort of mess after doing a zone transfer from certain hosts, e.g. $ dig +nocmd +nostats axfr dlv.isc.org @ns-int.isc.org dlv.new The complete zone is written to the output file, perfectly correct, but dig then sits there doing nothing. If one uses ctrl-C (SIGINT) it dies like this: dighost.c:3353: REQUIRE(sockcount == 0) failed. Abort (core dumped) Here's a stack trace from the core file, for what it's worth: $ pstack core core 'core' of 13457: dig +nocmd +nostats axfr dlv.isc.org @ns-int.isc.org - lwp# 1 / thread# 1 febc54d7 _lwp_kill (1, 6) + 7 feb713f3 raise(6) + 1f feb51709 abort(8047480, 6, 8249a88, febbe196, 8047360, 806db5a) + cd 081830d7 default_callback (81afbcc, d19, 0, 81afbbc) + 5b 0806db5a destroy_libs (8047364, feffb818, feffb818, 8047364, 8047480, 804739c) + c6 08067d95 main (6, 80473a8, 80473c4) + 105 08064b3e _start (6, 80474e8, 80474ec, 80474f3, 80474fc, 8047501) + 7a - lwp# 3 / thread# 3 febc47fb __lwp_park (82521c8, 8252198, 0) + b febbf058 cond_wait_queue (82521c8, 8252198, 0) + 3c febbf50a _cond_wait (82521c8, 8252198) + 64 febbf54c cond_wait (82521c8, 8252198) + 21 febbf585 pthread_cond_wait (82521c8, 8252198) + 1b 0819d78e run (8252190) + 62 febc44b7 _thr_setup (fea20a00) + 4e febc47a0 _lwp_start (fea20a00, 0, 0, fea0fff8, febc47a0, fea20a00) - lwp# 4 / thread# 4 febc5037 ioctl(8250260) + 7 febc44b7 _thr_setup (fea21200) + 4e febc47a0 _lwp_start (fea21200, 0, 0, fe9efff8, febc47a0, fea21200) This was with the 9.6.0-P1 version, but I've seen it with other versions. Fetching the signed root zone from na.iana.org also tends to behave like this. -- Chris Thompson Email: c...@cam.ac.uk ___ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
Re: Strange results from dnssec-dsfromkey
