intermittent BJ errors

rubyonrails-talk
1

hi all

I'm running background tasks using BJ 1.0.1 (gem version). On some requests, the tasks are executed as expected. On others, I get the following error:

RuntimeError (no bj found in ["/u/apps/igniter/releases/20080408205801/ script", "/bin", "/usr/bin", "/sbin", "/usr/sbin"]):

when it runs, it runs fine but does anyone know what could be causing these errors? I'm using ubuntu 7.10/nginix/mongrel/swiftiply

thanks nic

I'm experiencing similar problems on Ubuntu 8.04

Sorry for late reply, but the problem is rather curious...! The catch is in the word 'intermittent'... we had a lot of these errors in the last 2 weeks (when I was away :frowning: ) and users couldn't signup up!

I 'solved' the problem, by restarting THIN servers !?

Could you suggest a possible explanation? So it is not (an obvious) path problem it seems... because now it works... until it stops again...

Thank you! david

it seems perfectly obvious to me - you are starting your servers under two environments: one has bj in the and one does not. a likely scenario is starting from init scripts (machine boot)and from the console. in both cases you have to make sure you path is setup correctly.

Ara, thank you for the answer... but I don't quite get it... are you saying that two Thins are somehow running in different environments? I have to say that I don't see how this could be happening, because it's a Thin cluster and thus all/both instances stem from the same configuration. Please elaborate your thinking a little bit. Thanx again

Sorry for late response... You were right... After adding

export PATH=/usr/local/bin:$PATH

on top of /etc/init.d/thin script, BJ works fine after server restart.

Thank you. david
