Hi all, Over the last couple of days, a MySQL 4.0.21 server of ours has crashed a couple of times, with the error message listed below. It has previously been running without problems since being installed (about 150 days so far).
I've not had much luck in tracking down what "signal 6" means - the references I can find on the 'net seem to be from people running MySQL on a *BSD machine, while ours is on a RHEL3 server. Can anyone please point me in the right direction to track down what this might be? The server has 10GB of RAM, and MySQL has been compiled with -fomit-frame-pointer. I can re-compile MySQL without this option if it's absolutely necessary. Thanks, 050602 17:18:47 Out of memory; Check if mysqld or some other process uses all available memory. If not you may have to use 'ulimit' to allow mysqld to use more memory or you can add more swap space 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=8388608 read_buffer_size=2093056 max_used_connections=235 max_connections=800 threads_connected=190 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 3281785 K bytes of memory Hope that's ok; if not, decrease some variables in the equation. thd=0xc271010 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... frame pointer (ebp) is NULL, did you compile with -fomit-frame-pointer? Aborting backtrace! Trying to get some variables. Some pointers may be invalid and cause the dump to abort... thd->query at 0x1a70a218 is invalid pointer thd->thread_id=1642298 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.
