Hi all,
I'm running a debian woody with mysql 4.0.12 . Sometimes i get error 11 '
can't create new thead etc.... '
I search a lot on mysq.com and google but i found this is a problem only
with 2.2 kernels. I've also tried to use lastest mysql-max bineries from
mysql.com and i can't get more than 245 threads!
My server is a double Pentium xeon 1.8 GHz with 1Gb of RAM
My uname -a output is:
Linux mysql 2.4.22 #2 SMP Sat Sep 20 11:41:47 CEST 2003 i686 unknown

What's can be the problem? And also why with standard mysql binaries i

Thanks
