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, -- George Chelidze
