io-net npm-tcpip-v4.so hanging
Hey all,
I'm looking for a little bit of help in at least understanding why the below issue is occurring.
Over the past several months, we have been experiencing an issue where io-net (at least the TCP/IP portion) would hang
up and stop forwarding TCP/IP packets. More specifically
* Programs attempting to query the state of TCP/IP (netstat, ifconfig) would hang up, REPLY-blocked
* Programs attempting to connect to the server via TCP/IP (telnet/ssh) would fail to illicit any response (Rob/Jim
please confirm exactly what happens here?)
* The machine will sometimes still respond to ping (ICMP) but other times will not respond (Rob/Jim, any more details
on this?)
* QNX Native networking continues to work correctly
* A slay & restart of io-net resolves the issue completely - TCP/IP resumes normal operation
I have confirmed that in every instance, we're running npm-tcpip-v4.so from QNX6.3.0SP3, which has a size of 299788
bytes and an MD5: e89befdbd09d6ce7bc3134bb5afd2ec7
I am wondering, has anyone else experienced a problem with the TCP/IP stack similar to this? And is there a newer
version of npm-tcpip-v4.so that purports to fix this issue?
Thanks in advance,
James
