[OpenSIPS-Users] Memcache issues

[Bogdan-Andrei Iancu]

Brett,

I understand you are working with Vlad in troubleshooting the memcached 
issues.

But if I understand correctly, you are saying that you are also getting 
errors when using distributed dialog profiles but with couchbase ? If 
so, what kind of error you get there ?
