I have 3 primary servers (Windows 2k8 x64) with ZCM 10.3.4

I have created around 100 registration rules, but now I have more than 4000 registration rules! They have been duplicated automatically with no reason.

Now my primary servers are down, I can't do any zman command (for exemple to list or delete registration rules), and connection to ZCC is really difficult/impossible.

ZENServer process use 900Mo of RAM and 100% of processor
ZENLoader use 200Mo of RAM
CasaServer 100Mo

I have found an old TID about this, but there is no solution: Support | Registration Rules are showing as duplicates in ZCC

Any idea?
