Oscam restarts every 10-20 sec

Hello,
I am using oscam to descramble about 80 channels, i have 5 accounts with 50 possible connections per account.
it was working when i had a small number of channels (20 channels) didn't check it after that, when i put 80 channels now i have this error:

I used the configuration of oscam for red card (i copied the code as it is)

Sometimes oscam restarts also.. oscam version is 1.20-unstable_svn, build r10998 on tuxbox DM800SD.

Thanks for your answer
I have 80 connecstions or less.. all 80 connections comes from server next to it.
i have no idea why the ecm time is so high!
I need help..

Looks like the dm800se is having a hw issue.. as its too slow to load the login menu.. so i am changing the dm800 to a new one and will see what will happen.

Is there a maximum number of shared accounts for card? for example 100?

Thanks
