Hello,
After upgrading to Radiator 2.18.1, I noticed that on my radius server, I
have more than 2500 TIME_WAIT connections to my MySQL back-end database. I
didn't have this problem before (2.17.x), so I was wondering whether
something changed, with socket management, or anything else, starting
2.18.x. First I thought, it might have something to do with 2.18.1, but
downgrading to 2.18 doesn't help either. On my MySQL server, I can see
that the connections don't seem to stay open.. but the 2.18.1 appears to be
reconnecting all the time (2.17.1 leaves connection open). The MySQL
database isn't loaded at all, so that shouldn't be the problem.
On my 2.17.1 box, I have 0 TIME_WAIT connections, and the load on both
machine is exactly the same (and they're accessing the same database.
Did anyone see this problem before? And what can be done to fix this
behaviour (as there is a significant performance loss detected, on the AS
side).
Regards,
-Andy
PS: I have already tried tuning my TCP kernel parameters on Solaris (2.7),
but that doesn't help. Parameters on both machines are equal at this time.
