Hi,
Thanks for this hints. It looks like it was linuxthreads that was the
culprit. After rebuilding a statically linked binary with the patches to
the threads library from the mysql site it seems a lot more stable.
Given that this bug was known way back with Redhat 5.0 I'm rather
disappointed that Redhat _still_ haven't fixed this in the libraries
shipped with 5.2.
As rebuilding glibc from source is pretty painful (even on a 600 MHz
Alpha) I've put the mysql binaries up on
http://www.state51.co.uk/sharing/ in case these are useful for anyone
else.
Cheers,
John
