We have a problem with a box running 2.6.0-test11-mjb1 and supporting around 90k simultaneous TCP connection. After a few hours/days of running, when a lots of clients connects/disconnects, the conso
No experience with 90k TCP-flows but it seems GC is not able to free some the dst-entries for some reason. This will slowly kill your box with symptoms you describe. We have ask TCP-experts for timer
Let us assume, for the sake of back of the envelope calculations, that all 90k TCP connections speak to unique destinations. Let us further assume that all of them have at least one packet in flight.
Yes better tuning as gc_thresh and max_size is in better balance but max_size is same so I'll guess we collect unreclaimable entries util we see dst overflow still'. The long time before overflow is
Thanks all for your suggestions. Actually I have noticed that with 90k establish TCP sessions, I have around the double amount of entries in the routing cache. For each TCP session there is an inboun
