Hi, Iam having a mysql version 5.0.15-standard-log installed on redhat es4. It is configured as slave server. It was running fine till yesterday. Then it hit a mysql bug with signal 6. The mysql db was throwing the following errors on the shell prompt ie the OS shell prompt.
*** glibc detected *** free(): invalid pointer: 0x089e6843 *** *** glibc detected *** free(): invalid pointer: 0x089e6843 *** The mysql error log shows continuous occurence of mysql signal 6 and signal 11. The output of error log file is as follows: --------------------------------------------- mysqld got signal 6; 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=402653184 read_buffer_size=2093056 max_used_connections=0 max_connections=10 threads_connected=0 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 434135 K bytes of memory Hope that's ok; if not, decrease some variables in the equation. thd=0x89fd360 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=0x177f9c, backtrace may not be correct. Stack range sanity check OK, backtrace follows: 0x814e7f8 0x8787c8 (nil) 0x69840a 0x69eb3f 0x69eeba 0x81f8bb3 0x8240d56 0x824123a 0x82403cb 0x8166f0b 0x8168d82 0x81bf14b 0x81beb8c 0x8222586 0x8220387 0x872341 0x7046fe 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 0x89f1860 = drop procedure FHLMC.pool_info_select thd->thread_id=2 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. Number of processes running now: 0 060413 13:01:56 mysqld restarted Can anyone help me trace out the problem and how to go about the same ? Is it something related to glibc version that is causing the problem ? Thanks in advance, Abdul. ________________________________________ This email has been Scanned for Viruses! www.newbreak.com ======================================== -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
