Hello, I recently compiled Bind 9.9.6, on RedHatas follows: BIND 9.9.6-S2 (Subscription Edition) <id:eb5b129c> built by make with '--enable-threads' '--enable-fixed-rrset' '--disable-openssl-version-check' '--with-openssl=no' compiled by GCC 4.1.2 20080704 (Red Hat 4.1.2-52)
All seemed ok, except for 1 particular DNS server which had problems, getting messages in /var/log/messages at startup: Dec 1 10:23:24 clpi263 named[1297]: adjusted limit on open files from 16000 to 1048576 Dec 1 10:23:24 clpi263 named[1297]: found 12 CPUs, using 12 worker threads Dec 1 10:23:24 clpi263 named[1297]: using 6 UDP listeners per interface Dec 1 10:23:24 clpi263 named[1297]: using up to 4096 sockets ... ... ... Dec 1 10:23:25 clpi263 named[1297]: socket: file descriptor exceeds limit (4096/4096) Dec 1 10:23:25 clpi263 named[1297]: set up managed keys zone for view V049, file '/etc/namedb/Data/MKeys/98296d0c75d7c474f605af1e9e8f6bb6c7aa336f12e022a1819a891c73ae34d9.mkeys' Several of my views on that server had this message. I also found this in my normal DNS log file: 01-Dec-2014 11:45:35.473 general: critical: adb.c:2926: REQUIRE((options & 0x00000003) != 0) failed, back trace 01-Dec-2014 11:45:35.473 general: critical: #0 0x413e0b in assertion_failed()+0x4b 01-Dec-2014 11:45:35.473 general: critical: #1 0x5c319a in isc_assertion_failed()+0xa 01-Dec-2014 11:45:35.473 general: critical: #2 0x476ed4 in dns_adb_createfind2()+0x1044 01-Dec-2014 11:45:35.473 general: critical: #3 0x5336c7 in findname()+0xe7 01-Dec-2014 11:45:35.473 general: critical: #4 0x5392d5 in fctx_getaddresses()+0x3b5 01-Dec-2014 11:45:35.473 general: critical: #5 0x53ce5a in fctx_try()+0xcca 01-Dec-2014 11:45:35.473 general: critical: #6 0x543bb8 in fctx_start()+0x1a8 01-Dec-2014 11:45:35.473 general: critical: #7 0x5e2d1c in run()+0x2bc 01-Dec-2014 11:45:35.473 general: critical: #8 0x3a91407851 in _fini()+0x3a90e0e889 01-Dec-2014 11:45:35.473 general: critical: #9 0x3a90ce811d in _fini()+0x3a906ef155 File descriptor limit info: ulimit -nS 1024 ulimit -nH 4096 my named process /proc//limits data is: Limit Soft Limit Hard Limit Units Max cpu time unlimited unlimited seconds Max file size unlimited unlimited bytes Max data size unlimited unlimited bytes Max stack size unlimited unlimited bytes Max core file size unlimited unlimited bytes Max resident set unlimited unlimited bytes Max processes 256388 256388 processes Max open files 1048576 1048576 files Max locked memory 65536 65536 bytes Max address space unlimited unlimited bytes Max file locks unlimited unlimited locks Max pending signals 256388 256388 signals Max msgqueue size 819200 819200 bytes Max nice priority 0 0 Max realtime priority 0 0 Max realtime timeout unlimited unlimited us I don't get this problem anywhere else, only on this 1 particular DNS server. It has many different views, and 15x virtual IPs, so I know it is a complex configuration. My previous version was bind 9.8.6-P1 which ran just fine. I have read much information, but can't seem to put my finger on the solution. I strongly suspect some type of O/S limit issue, not a problem with the Bind code. Help Blair Porter AT&T
