Subject: USR2 + QUIT sometimes interrupts socket connections
Date: Fri, 19 Aug 2011 15:46:28 -0700 [thread overview]
Message-ID: <CAB3oGjpb89FYCqmrR1MtrG+kBsgvmjbdja+1Y+bu5_jKAYUojw@mail.gmail.com> (raw)
I've seen this happen a few times during deploys/restarts, and I just
got a fresh backtrace, so I thought I'd bring this up.
The exception message I get is: Mongo::ConnectionFailure: Failed to
connect to host xxx.yyy.zzz.com and port 12345: Interrupted system
call - connect(2)
Basically, it looks like unicorn is interrupting connect(2) calls when
an underlying library is making a socket connection.
Backtrace: https://gist.github.com/1158216
Mongo pool.rb: https://github.com/mongodb/mongo-ruby-driver/blob/1.3.1/lib/mongo/util/pool.rb
I don't know if this is a unicorn thing or a Mongo implementation
problem, but I'm pretty sure I've seen this happen before with
Net::HTTP. I'll try to locate that error.
