I did not try the tcp_tw_reuse, because I am a bit fuzzy on what that exactly
does. That is, what is the difference between recycling and reusing?
The man page for tcp just mentions that tcp_tw_reuse allows to reuse TIME_WAIT
sockets if it is safe from the protocol viewpoint and that it should n
Friso,
You may be knowing this already, but please bear in mind there is a
potential risk of packets from previous connections that were in flight reach
the new connections (that's the reason for the TIME_WAIT state in TCP).. And
that may lead to unexpected behaviour..

Might be worth trying tcp_tw_reuse before turning on tw_recycle - as I
understand it, the former is a lot safer than the latter.
Can't wait for HDFS-941 some day :)

tcp_tw_recycle did not do what you needed?

Friso,
This is very interesting, and nobody answered probably because no one
tried tcp_tw_recycle. I personally didn't even know about that config
until a few minutes ago ;)
So from the varnish mailing list, it seems that machines behind
firewalls or NAT won't play well with that config, but I do
Hi all,
Since I got no replies to my previous message (see below), I went ahead and set
the tcp_tw_recycle to true. This worked like a charm. The number of sockets in
TIME_WAIT went down from many thousands to just a couple (tens). Apparently,
once set to true, the recycling happens quite eager
Hi all,
We are experiencing a lot of "java.net.BindException: Cannot assign requested
address", which is a case of https://issues.apache.org/jira/browse/hbase-2492.
At some point, all grinds to a halt and regionservers start to shut down.
I was wondering if anyone has found a way around this pro
