Shouldn't CRASH httpd children right?! P.S. I had crashes with 4.0.2, 4.0.3 and 4.0.3pl1 as well. I reverted back to 4.0.1pl2 and the crashes happened less often. That is when I broke down and ran gdb on the setup. It crashes pretty consistently now every 2-3rd time the script is called. When I reloaded the script 25 times, I got 12 seg faults in the error_log. E_ALL error logging is turned on and I get no warnings or anything in the php error log. Is my simple PHP script the (valid) cause of this? Any help appreciated:) --------------------------------------------------------------------------- Full Bug description available at: http://bugs.php.net/?id=7326
