Do you by any chance have a "statefull" firewall between your radius server 
and database?

There _may_ be a problem with rlm_sqlippool in 1.1.4 (it is marked as an 
unstable module in 1.1.4)
If at all possible please consider updating to CVS head as there has been 
allot of work on sqlippool and the postgresql driver. In-fact the latest 
version of sqlippool _should_ work on Oracle (which I remember you wanted to 
do previously) although I have not tested this functionality. (rlm_sqlippool 
in 1.1.4 relies on a bug in rlm_sql_postgresql to work, hence the reason it 
doesn't work properly with other DBs)

Alternatively you could backport the cvs head version of sqlippool to 1.1.4 
which is something I have been considering for the 1.1.5 release but have 
yet to find the time to do (but would happily accept donations to do so :-)
