maximum-timeout in ippool do not work?

[Yanrui Hu]

Guys,
I recently use rlm_ippool to let freeradius assign strongswan user ip.
By ACCT-STOP, freeradius can release the ip that assigned to user.
But for the case that accounting packet lost, we need a timeout mechanism.
But in ippool file, I set maximum-timout, but it do not work. the ip was
not released even that user already lost for a long time.
Any suggestions?
