Load balanced configuration unable to access Admin -> Manage jobs?
I have had good success in setting up a load balanced configuration with nginx except that I get the following error when accessing Admin -> Manage jobs: "This Galaxy instance is not configured to run jobs. If using multiple servers, please directly access the job running instance to manage jobs." When I access the runner instance directly at <http://localhost:8079/admin/jobs>, the browser just hangs with no response. A quick search of the wiki and the dev mailing list archive didn't turn up a solution, so any help would be appreciated. Thanks, Olen
Problem solved: I found this stack trace in the job runner's log: Traceback (most recent call last): File "./scripts/paster.py", line 34, in <module> command.run() File "/home/galaxy/galaxy-dist/eggs/PasteScript-1.7.3-py2.6.egg/paste/script/command.py", line 84, in run invoke(command, command_name, options, args[1:]) File "/home/galaxy/galaxy-dist/eggs/PasteScript-1.7.3-py2.6.egg/paste/script/command.py", line 123, in invoke exit_code = runner.run(args) File "/home/galaxy/galaxy-dist/eggs/PasteScript-1.7.3-py2.6.egg/paste/script/command.py", line 218, in run result = self.command() File "/home/galaxy/galaxy-dist/eggs/PasteScript-1.7.3-py2.6.egg/paste/script/serve.py", line 303, in command serve() File "/home/galaxy/galaxy-dist/eggs/PasteScript-1.7.3-py2.6.egg/paste/script/serve.py", line 287, in serve server(app) File "/home/galaxy/galaxy-dist/eggs/PasteDeploy-1.3.3-py2.6.egg/paste/deploy/loadwsgi.py", line 151, in server_wrapper **context.local_conf) File "/home/galaxy/galaxy-dist/eggs/PasteDeploy-1.3.3-py2.6.egg/paste/deploy/util/fixtypeerror.py", line 57, in fix_call val = callable(*args, **kw) File "/home/galaxy/galaxy-dist/eggs/Paste-1.6-py2.6.egg/paste/httpserver.py", line 1314, in server_runner serve(wsgi_app, **kwargs) File "/home/galaxy/galaxy-dist/eggs/Paste-1.6-py2.6.egg/paste/httpserver.py", line 1264, in serve threadpool_options=threadpool_options) File "/home/galaxy/galaxy-dist/eggs/Paste-1.6-py2.6.egg/paste/httpserver.py", line 1118, in __init__ **threadpool_options) File "/home/galaxy/galaxy-dist/eggs/Paste-1.6-py2.6.egg/paste/httpserver.py", line 1024, in __init__ **threadpool_options) File "/home/galaxy/galaxy-dist/eggs/Paste-1.6-py2.6.egg/paste/httpserver.py", line 588, in __init__ % (spawn_if_under, nworkers)) AssertionError: spawn_if_under (5) should be less than nworkers (3) Per the Scaling and Load Balancing instructions [1], I had used the following stanza for the job runner: [server:runner0] use = egg:Paste#http port = 8079 #host = 127.0.0.1 use_threadpool = true threadpool_workers = 3 The value for threadpool_workers (3) conflicted with the default value for local_job_queue_workers (5).

Per the Scaling and Load Balancing instructions [1], I had used the following stanza for the job runner:
[server:runner0] use = egg:Paste#http port = 8079 #host = 127.0.0.1 use_threadpool = true threadpool_workers = 3
The value for threadpool_workers (3) conflicted with the default value for local_job_queue_workers (5). When I increased the value of threadpool_workers to 5, the runner's web interface came right up.
Hi Olen, Thanks for finding this! I've increased the value in the documentation to 5. --nate
