Minor Description
Switching to "untyped" socklnd connections by using the following option
options ksocklnd typed_conns=0
appears to make socklnd unable to communicate. Self-pinging fails:
lnetctl ping 192.168.122.123@tcp
manage:
- ping:
errno: -1
descr: failed to ping 192.168.122.123@tcp: Input/output error
Typical net debug trace is
