I don't know how to repeat this problem, so, I don't know if I can reproduce in 5.1.61

Thank you for the feedback. Please send us full error log file: I want to see why crash initially happened.

120306 16:20:01 - 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=1073741824 read_buffer_size=262144 max_used_connections=533 max_threads=1200 threads_connected=20 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 11198588 K bytes of memory Hope that's ok; if not, decrease some variables in the equation. thd: 0xab2ed30 Attempting backtrace. You can use the following information to find out where mysqld died.

I guess file descriptors get corrupted or mixed up in memory. I've seen also mysql error log content being written directly into MYD tables under harsh circumstances...

Seen once again on OSX 10.6.8 with MySQL 5.5.30 after an innodb assert: [ERROR] Failed to open log (file '11:22:33 UTC - mysqld got signal 6 ;', errno 2) [ERROR] Could not open log file [ERROR] Can't init tc log [ERROR] Aborting

Hit the same bug today after hitting bug http://bugs.mysql.com/bug.php?id=70327. Server version on MASTER: 5.6.13 Can someone change Version number from 5.1.50 to (at least) 5.6.13? If you need full log file entries please let me know.

Re-opening since more users see it. All who see the bug, please, send us your OS detils: accurate version of OD, version of glibc.

All reporters: Please let us know if you have any plugins loaded. For example innodb plugin (5.1), thread pool plugin, semisync, PAM auth, audit log plugin, or third party plugins.

so my theory is some code does a double close() of a file descriptor which leads to other thread reusing it for wrong purpose. i believe that my_file_close results should always be checked and handled. and all closed fd's should be set to -1 (under proper locking to avoid races).
