This problem could not be duplicated once I upgraded to glibc-2.1.2-2.i386.rpm The memory leak and NULL pointer both went away. This problem appears to be resolved. well this doesn't fix the problem for a stock 6.0 RH distro so perhaps the kernel upgrade is also required. # netstat -a Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State ... udp 65456 0 *:2049 *:* ...
