主题: Re: cluster mode crash on 3.2.0?
please change the following option:
CONFIG proxy.config.http.share_server_sessions INT 1
the default '2', which is thread pool, is not safe in some case in this
version.
and feed back please

Re: 回复： cluster mode crash on 3.2.0?
Posted by "ming.zym@gmail.com" <mi...@gmail.com>.
I am not sure what is your use case, but as far as we know, in some
situation TS is unsafe, for example: the transform usage & Range etc.
we are using the following codes in the production, which don't crash
that much. we do not use any plugin.
https://gitorious.org/trafficserver/taobao/commits/3.2
please try it if you just want a working cluster :D
we will make more codes into git/master if we are ready, some of the
performance patches is not in the official tree right now.
FYI
