Here's an entry from the archives where Alan (sort-of) suggests using rlm_sqlippool to fix the same problem you're having:

SQL does appear to have better performance/

Subject: rlm_ippool vs rlm_sqlippool
Greetings,
We use rlm_ippool for pool management. Each pool is configured with 16K addresses. About 10K are used in the peek time (per pool).
I believe we have almost reached our IO capacity, because heavy IO operations like gzipping a 300M file cause freeradius to throw errors like:
Error: Discarding duplicate request from client C port 65038 - ID: 109 due to unfinished request 34797335
Error: Discarding duplicate request from client C port 65035 - ID: 98 due to unfinished request 34797336
and a bit later:
Error: WARNING: Unresponsive child for request 34797366, in component post-auth module ippool-A
Error: WARNING: Unresponsive child for request 34797382, in component post-auth module ippool-A
Will it make any sense to switch to rlm_sqlippool? Will it be less IO sensitive?
I know it's worth a try, however any additional information would be helpful.
Thank you in advance,
