HotSpot and user manger server goes down

Hi ALL.
Like I did some post before with interface problem like losing packets .
Now my server is going down every two hours or at least once a day goes down.
I have like 700 people online and on the pick time the server reach like 40 Mbits and will not keep that for long will freeze . I have to reboot or other way will not come up or you can’t logon nothing until you reboot.
Anyone has idea for this will help me a lot thanks.

thx selim ..

Make sure problem is not related to hardware.
You can contact support with attached support output file [that was generated after reboot].

Hi Sergejs
I have changed the PC still was doing the same think. Now I have slip the traffic on two server I build up two user manager, and still doing the same going down after two or 1 day work. I don’t know is just freezes and I have to do physically reboot, i can’t login i can’t ping I can’t do anything until I reboot.I thought is the traffic problem but i don’t think so. How much packet throughput Mikrotik OS support.
I’m using OS v 3.10 and I’m thinking to upgrade on v 3.11 to see if it make any different.
I don’t know where to go and check where can I find the errors after reboot. In log or where don’t know.

Sincerely
Selim.
