[SR-Users] Weird IPv6 Registration Issue

Hi

I am experimenting with a dual homed (IPv4 and IPv6) Openser 1.1.0-tls server.

If I register using a IPv6 address then the initial registration works
and the details are saved in the location table. However when the UA
trys to re-register on expiry the SIP returns a 200 OK but the
location data is not updated in the table. Looking at the syslog it is
reporting that it didn't save the data as there was an existing entry
on index with key 1. This is referring I presume to the primary index
on "username, domain, contact) on the location table.

So what happens is the first location entry expires and gets deleted
from the table and thus there is no record for the subsequent register
and thus openser thinks the UA has dropped off until the next
re-register when because there is no longer a location record the data
gets saved correctly.

This doesn't happen if I register the same UA on IPv4 on the same
openser server.

Anyone got any ideas why this is happening?

Regards

Jon
