Hi all! I had a problem with Radius server on Saturday, and after a lot of searching I have not found an appropriate answer on the Web. I will be submitting the log file that contains the problem that I have been working on.

One thing I noticed is that the server did accept connection requests during the time of the problem. I found some answers but just wanted to see If anyone else had the same problem. I read that it can be a memory allocation issue, but just wanted to confirm. Also, I would like to know what could be done to solve this problem? Thanks and best regards to all, Marko
