IP Allocation FAILED

[battossai]

Hi,

What should i do if some user get disconnected but don't get their ip again.
I've set up allocation 1 ip to that user, but when get disconnected did not
get the correct ip, in fact the user get another ip.
It seems that the ip still active on radippool table, i have set up lease
time for 300 second.

Is there any clue how to fixed up this ?
I give log from this issue.
Thanky you in advanced.
