$result=mysql($database,"select tcode from thenet $index $index1");
$datanum=mysql_numrows($result);

when $resule nothing
then mysql_numrows($result) whill  crash mysqld
system display  this error message
pid 24903 (mysqld), uid 0: exited on signal 11

use php-3.0.5 & 3.0.6 have the same problem
mysql-3.21.33 & 3.22.13

i compiled mysql use freebsds threads lib like this
--with-named-thread-libs=-lc_r

is this touch off this problem ??
