Max Connections Limit

[chrisming520]

Hi experts:
I have 3000,0+ users , when 1500 users connect radius server  at same time , all
 can be authenticated .  but if there are more than 1500 users,the rest (some of
 them ) can not get connect to server , get error like : NO REPLY FROM SERVER .
can you tell me how to solve this problem ? thank you in advance .
looking forward your answer
Best regards
Chris:-)
