Oscam server frezing problems

I run a small oscam server (7 peers) on my Vu Duo2 with latest Blackhole image and Sky Uk Freeview card with BT Sports (0960). Everything has been fine until the last few days. My peers are complaining of high ecms. I also get a lot of freezing when watching sky channels from one of my peers. I`ve tried all sorts of ways to get this sorted but I really don`t know what I`m doing. The only thing that stops the freezing at my end is when I change the group number from being the same on both servers and clients. But then it looks like my peers are offline, not sure if they are. I`ve posted below edited sections of my cfgs, if someone would be kind enough to see what I`m missing:

Thanx for any help given.

I`m pretty sure my problems are because of the group numbers I have for the servers and users. I don`t understand what is the correct number I`m supposed to give each reader/account. I`ve been at this for days, reading everything I can, but there is no one way to do it. All the info I find just changes from other info I find.

Well I`ve now managed to make my server unwatchable. I don`t have any issues with my local card, I can watch the channels it clears without any freezing. But I have big freezing problems when I watch channels my peers give me. It switches between cache1( I don`t know if I can disable this option) to all my peers who have these channels. I believe if I`m having issues then so are my peers from me.

I`ve studied the oscam wiki page all day and it hasn`t helped at all. I`ve made all the adjustments(if any) to the required fields and there is no difference. All I know is, when I enable the users/clients in oscam the glitching/freezing starts. I`ve tried enabling them 1 by 1 to see if it`s anyone client in particular that`s causing it but it doesn`t matter who I enable/disable.

Thanx lacierva. I was contemplating doing that after reading the wiki and trying to work out what the group numbers mean. I think I`m right in thinking ,if all my users/clients have the same group number assigned to them, then they`ll overload the reader that has that group number causing freezing? Anyway I have done as you say and already there is a difference at my end, I just hope my clients /peers are seeing the benefit.

Thanx bud.
