Re: [SR-Users] Database errors with usrloc db_mode=1 and dmq_usrloc

Ok so my findings so far: 1- db_mode=2 --> No errors. 2- db_mode=1 --> The reported error. 3- modparam("usrloc", "server_id_filter", 1) --> Irrelevant, errors happen with or without it on db_mode=1. Anything else I can try in order to find out what is happening? My next step was to enable mysql logs or capture traffic and see what exactly is Kam sending... Let me know your thoughts. Thanks,  Joel.

I tried moving the VIP from NodeA to NodeB, and the error stops happening on NodeA, and starts happening on NodeB. I did not see this happening with db_mode=2, and I *think* it started happening when I enabled the server_id related params? I'm not 100% sure of this so I'm going to try some different combinations to see if I can narrow it down a little and provide more accurate details for you guys to find the issue. I'll report back shortly... Thanks!  Joel.
