Ive found some articles online, nothing of substance however. Only descriptions offered are very vauge like responsible for "switch ethernet traffic". And as a follow up, why would that task suddenly jump on devices from <5% to > 90% then locking up a switch.
Did, no loops. We even disabled all ports on LAN rtr (the device being bad here) except for the WAN uplink, still did it.....I think, we tried so many things. I know we swapped the device out entirely, same issue. I cant for certain say disabled all ports, a co-worker took over some of the troubleshooting at times. Here an even better one tNetTask is the central clearing house for all network I/O. A packet comes in, netJobAdd'ed, and tNetTask does everything for the packet for its lifetime. This is done for all packets, all network interfaces, and the entire TCP/IP stack.
