Mysql Crash

Seems to say in the error log that it is going to need 244.49mb of ram. Having only 192, would this cause mysql to crash in this way?

Any way you could suggest for me to optimize the settings?

MYSQLD.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.

keybuffersize=33554432

readbuffersize=131072

maxusedconnections=1

max_connections=100

threads_connected=1

It is possible that mysqld could use up to

keybuffersize + (readbuffersize + sortbuffersize)*max_connections = 250367 K

bytes of memory

Hope that's ok; if not, decrease some variables in the equation.

thd=(nil)

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=0x4327a628, backtrace may not be correct.

Stack range sanity check OK, backtrace follows:

0x80fb511

0x4015a685

0x8106621

0x40155041

0x4039ab8a

New value of fp=(nil) failed sanity check, terminating stack trace!

Please read http://www.mysql.com/doc/en/Usingstacktrace.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

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.

Caker has posted a somewhat more optimized configuration for MySQL here about 12 posts down:

Actual settings:

http://www.theshore.net/~caker/uml/my.cnf

Those settings should work better with Linode configurations.

I changed some settings based on that file, to larger values of course. I hope this stops the crashing.

still crashes, same error and I have very limited settings, 25 max_connections… any ideas?

@caker:

Try adding "set-variable=threadcachesize=40" under the [mysqld] section of your mysql config file.
You've done that, and it still crashes? Have you verified that it's actually loading the settings?
