Body
copied!<p>Some backstory:</p> <p>My server ran out of disk space last night while delayed_job workers were running off jobs processing images. </p> <p>When I try to stop the workers, I get the response "Terminated". </p> <pre><code>RAILS_ENV=production script/delayed_job stop Terminated </code></pre> <p>Then I run the following to see that the workers were terminated. </p> <pre><code>ps -ef | grep delayed_job servername 4474 4274 0 02:37 pts/1 00:00:00 grep --color=auto delayed_job </code></pre> <p>Now I try to start up new workers. </p> <pre><code>RAILS_ENV=production script/delayed_job -n2 start ERROR: there is already one or more instance(s) of the program running ERROR: there is already one or more instance(s) of the program running </code></pre> <p>This is the error that I'm getting, I'm not able to start any new workers even though it seems that I have stopped all active workers. </p> <p>This was confusing me so I ran </p> <pre><code>RAILS_ENV=production script/delayed_job status delayed_job: running [pid 0] delayed_job: running [pid 0] </code></pre> <p>This seems wrong [pid 0], it seems like my workers have been corrupted and I'm hoping to figure out how to solve this issue. Thanks!</p> <p>I'm running on Linux Ubuntu LTS 10.4. </p> <p>EDIT: So I deleted the 2 worker files I found in tmp/pids which allowed me to start and stop workers. However, the workers will not run anything because I believe I need to have PID files generated in the tmp folder. </p>
