Description:
Upon starting the mysql server from the binary rpms, it gives this warning message:

[Warning] Asked for 196608 thread stack, but got 126976

If I recompile from source, I do not get this warning.

I am running Red Hat Enterprise Linux 3 WS release 3 (Taroon Update 4) with a 2.4.21-27 smp kernel.  

This can also be created on a Red Hat 7.3 machine running a 2.4.18-19.7 smp kernel.

How to repeat:
Simply install the rpm or run the mysqld command.

Suggested fix:
This seems to be an incompatibility with the pthread library that is statically compiled in to the binary mysqld executable.  Perhaps looking at the library which is statically linked in would be a good place to start.

Also, it is unclear how dangerous this warning is.  If it is benign, it might be worth adding something to the documentation.

Thanks in advance for any time and help on this issue.

Yes this happens because the server was statically linked with a fixed thread stack size and of course that warning message need to be documented.

This is a duplicate of #6226.
