[chef] Re: Re: EOFError when decrypting data bags

[Dennis Lovely < >]

We experience infrequent EOF errors during node.save on successful runs. Will read your notes thanks Lamont!

These are some notes I wrote to myself to capture some of the recent EOFError issues we've been seeing:

So far they all seem to be related to networking issues on large packets with proxies and/or MTU issues.  Those issues mostly did not clear up on a retry, though, other than when the connection to S3 hiccup'd, so none of that may help your case.  You'll probably need to collect full stack traces, ideally tcpdump's on both ends, if you can get server logs from a relatively quiet server when the client errors that could be useful (but probably not so useful if its interleaved with dozens of other clients converging).

And there's nothing I'm aware of in 11.12.8 -> 11.14.6 that would cause this behavior to change (openssl versions most likely got bumped, but there's no known issues with more recent openssl spitting out more EOFErrors).

Ohai chefs!

Recently after upgrading to chef client 11.12.8 -> 11.14.6 we are seeing
frequent EOFError's when decrypting an encrypted data bag.  We are running chef
server 10.28.X.  A subsequent run usually clears it up which makes it hard to
debug.  The failure looks like so:

[2014-09-11T22:21:07+00:00] DEBUG: Re-raising exception: EOFError - end of file
reached
/opt/chef/embedded/lib/ruby/1.9.1/openssl/b

Anyone running into this or may have an idea why?

Thanks,
