Hi! I've run into a problem with a replication setup. I have a 4 CPU EV5.6 AS4100 running a master database. MySQL is 3.23.36, OS is Tru64 4.0F patchkit 4. MySQL is compiled with Compaq CC & C++ with the recommended compiler options mentioned in INSTALL-SOURCE. This master database runs without any problems. Today I setup a slave server on a 12 CPU EV67 GS140, still 4.0F patchkit 4 and MySQL 3.23.36, and still compiled with Compaq CC & C++. When starting up the slave I immediately get this : Unaligned access pid=892 <mysqld> va=0x12021d4e4 pc=0x3ff800e8a24 ra=0x3ff8013df90 inst=0xa6100028 010406 15:47:23 mysqld restarted Unaligned access pid=875 <mysqld> va=0x12021d4e4 pc=0x3ff800e8a24 ra=0x3ff8013df90 inst=0xa6100028 010406 15:47:23 mysqld restarted Unaligned access pid=881 <mysqld> va=0x12021d4e4 pc=0x3ff800e8a24 ra=0x3ff8013df90 inst=0xa6100028 010406 15:47:24 mysqld restarted And in the error log : 010406 15:36:16 mysqld restarted /usr/users/un19102/mysql/libexec/mysqld: ready for connections mysqld got signal 11; The manual section 'Debugging a MySQL server' tells you how to use a stack trace and/or the core file to produce a readable backtrace that may help in finding out why mysqld died. I start it with safe_mysqld and this script try to restart it over and over again. I have also tried starting it manually. Same result. Sometimes however it does startup, but crashes within 5-10 minutes with the same error. I tried compiling with GCC instead of Compaq CC/C++. Same result, same error. I've also tried various mysqld parameters to turn off dangerous settings and/or add more debugging info. I didn't try yet to compile MySQL with more debugging options etc. As soon as I remove the slave settings from my.cnf and start it as a normal server, everything runs normally. Is it compiler related problems, or is there something wrong with the slave option ? -- Un saludo / Venlig hilsen / Regards Jesper Frank Nemholt Unix System Manager Compaq Computer Corporation Phone : +34 699 419 171 E-Mail: [EMAIL PROTECTED] --------------------------------------------------------------------- Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?
