Hi, I use MySQL 4.1.10, and it crashes about once a day. I posted about this bug two days ago, but I forgot to put the stack trace result there, sorry for that. Now I put the stack trace result below.
My kernel is 2.6.10, RAM is 4 GB. Single CPU with HT (shows up as 2 CPU on linux). The MySQL that I use is the official RPM from mysql.com. Here is what I found in my error log: --- start: hostname.err ---- mysqld got signal 11; This could be because you hit a bug. It is also possible that this binary or one of the libraries it was linked against is corrupt, improperly built, or misconfigured. This error can also be caused by malfunctioning hardware. We will try our best to scrape up some info that will hopefully help diagnose the problem, but since we have already crashed, something is definitely wrong and this may fail. key_buffer_size=33554432 read_buffer_size=2093056 max_used_connections=80 max_connections=400 threads_connected=4 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 3209660 K bytes of memory Hope that's ok; if not, decrease some variables in the equation. thd=0x56000440 Attempting backtrace. You can use the following information to find out where mysqld died. If you see no messages after this, something went terribly wrong... Cannot determine thread, fp=0xbfe5f5a8, backtrace may not be correct. Stack range sanity check OK, backtrace follows: 0x808d8d7 0x82e68d8 0x80929a3 0x809af45 0x809b709 0x82e408c 0x830d95a New value of fp=(nil) failed sanity check, terminating stack trace! Please read http://dev.mysql.com/doc/mysql/en/Using_stack_trace.html and follow instructions on how to resolve the stack trace. Resolved stack trace is much more helpful in diagnosing the problem, so please do resolve it Trying to get some variables. Some pointers may be invalid and cause the dump to abort... thd->query at (nil) is invalid pointer thd->thread_id=7005520 The manual page at http://www.mysql.com/doc/en/Crashing.html contains information that should help you find out what is causing the crash. --- end: hostname.err --- And here is the stack trace result: [EMAIL PROTECTED] ~]# resolve_stack_dump -s mysqld.sym -n mysql.stack1 0x808d8d7 handle_segfault + 423 0x82e68d8 pthread_sighandler + 184 0x80929a3 ip_to_hostname__FP7in_addrPUi + 483 0x809af45 check_connection__FP3THD + 213 0x809b709 handle_one_connection + 297 0x82e408c pthread_start_thread + 220 0x830d95a thread_start + 4 Does anyone have the same problem? How do I fix this? Thank you very much. Regards, --bk -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
