MySQL should not crash, as long as you have a bug free glibc library!

What Linux system are you using. Do you have the latest glibc
libraries?  (Note that if your system is not stable, you may get 
similar problems with any other sql server that uses threads!)

Have you compiled MySQL yourself or do you use a pre-compiled binary ?

(Please always use the mysqlbug script when posting questions as this
includes a lot of information about your setup that is needed to be
able to answer your questions!)

You can find a lot of suggestions to this problem at:

section: 'What to do if MySQL keeps crashing'

If you really need fast explicit help, you should consider taking
MySQL email support.  We try to help everyone but our recourses are
quite limited and we must prioritize paying customers.
