BJ - Reaping 1 threads for slow workers because of 'shutdown'

I’m calling Bj from inside a controller in rails.

controller code

http://pastie.org/239415

Its running a simple script that logs the user to the database.
Obviously this isn’t a good candidate for a background job, this is
just something simple I’m using to test.

bj script code

http://pastie.org/239418

When I shutdown rails, I get a timeout error from mongrel

log snippet

http://pastie.org/239419

Any ideas why mongrel is holding on to that thread? I am calling
exit_success! at the end of my run action in the bj script, it appears
the script is exiting properly.

I also find it strange that the sessions_controller is referred to in
that backtrace.

Any ideas?

Thanks

Here is an update. I tried in development vs production and that
didn’t make a difference. However, I only saw this behavior on
mongrel. On thin and webrick it would quit quickly.

it’s a mongrel bug - mongrel tries to reap threads it does not own.
nothing to do with bj and you can safely ignore.

Great. Thanks.

BTW - I’m having fun with Bj. Thanks for writing it!

But what’s the solution to it delaying the shutdown of mongrel?

patch mongrel.

bj doesn’t delay the shutdown - it merely creates a thread which
mongrel insists on reaping. the fix is for mongrel not to reap
threads it hasn’t started.
