Closed as program error.
Error description
Setting "receive_q_elem" to a high value on the CT3 (RedRiver) adapter causes a hang in ifconfig. The hang is caused because the memory requested by the adapter is bigger than a heap segment (256MB). The hang can occur during ifconfig at bootup (causing a boot hang) or when running ifconfig is done at the command line after changing the variable to a high value.
Local fix
The workaround for this problem is to leave "receive_q_elem" at its default value of 4096. Values higher than 19,0000 are expected to cause the hang.
Problem summary
Setting "receive_q_elem" to a high value bigger than a heap segment (256MB)on the CT3 (RedRiver) adapter causes a hang in ifconfig.
Problem conclusion
Correct the netmalloc code such that ifconfig will not hang, when memory requested by the adapter is bigger than a heap segment (256MB)
Temporary fix
