rlm_ippool vs rlm_sqlippool

[George Chelidze]

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,
