Getting weird errors when trying to send a message through Twilio

We made a big upgrade to our backend yesterday and now we're getting some weird errors and I have no idea what they are. The errors seem to be happening when trying to send a message via Twilio's client. Also, things are getting backed up in our sidekiq queue we believe because of these errors. Our sidekiq busy tab has a few things waiting there. Here are some of the errors we're seeing:

  • IOError: closed stream
  • OpenSSL::SSL::SSLError: SSL_connect returned=1 errno=0 state=SSLv3 read server hello A: unknown alert type
  • Net::ReadTimeout: Net::ReadTimeout
  • EOFError: end of file reached
  • IOError: attempt to read body out of block
  • Errno::EBADF: Bad file descriptor

These haven't happened for us much in the past and now they are happening very frequently. Here's a stacktrace for the IOError: closed stream error:

Most likely found the issue since we haven't had any problems since fixing it this way. Turns out the Twilio Client is not thread safe and we were trying to hammer the same @client with a bunch of different threads. The fix was to make sure that we create a new twilio client every single time we need one.
