Following the manpage example, I set default threads to use libthr instead of libc_r. Running a fairly hi load web/mysql server, I ended up with with the error "unable to create new threads" and and had to kill the mysql server. It seems that mysql is partial to libc_r rather than libkse or libthr(?) as changing the libmap entry back to libc_r for default cured the mysql woes. Sven
