Not to hijack Dave's thread, but I started having this issue again two days
ago. Except this time, I am not getting any DB handle errors. This is all I
see in radius.log:
Wed Sep 4 20:54:22 2013 : Error: Discarding duplicate request from client
158.104.249.7 port 32768 - ID: 82 due to unfinished request 10895
I see a lot of these, then it handles a few more requests and then dies.
>From what I can tell, this indicates a slow backend DB, but I have it
running on a separate VM with 4GB of RAM and 4 cores. MySQL spikes 100%
regularly on one CPU, memory is about 70% used. I"ve done all the MySQL
Tuning changes in the Admin guide. At this point, I've had to pull our PF
from production, as it isn't stable enough.
I have two core dumps from freeradius from when it crashes, but I haven't
been able to get anything useful out of them. Would anyone be interested in
seeing those? I am going to see if I can compile FR from source with
--enable-developer so I can more useful info in gdb. I might also switch to
RHEL and see if that has anything to do with it.
