[SR-Users] usrloc - ka_mode timeout

[Daniel-Constantin Mierla]

Hello,

have you watched for how long it stays in memory? The usrloc keepalive
should leverage the same mechanism that was used by the keepalive done
by nathelper module, it should not delete the record immediately, but
after ka_timeout elapsed from the last received keepalive, then expires
is set to current timestamp + 10 seconds, so the next timer cleanup
should remove with.

Can you get the kamctl up dump for the phone you tested with? The
keepalive related attributes (last keepalive timestamp, last rtt) should
be in the json output/

Cheers,
Daniel
