Long running task will stop randomly #7

Closed shivanraptor closed 9 years ago

shivanraptor commented 9 years ago

I use this buildpack to run a long-running CasperJS task with the following command:

~$ heroku run casperjs long.js > log.txt

but the task stops randomly, without leaving any error message. Sometimes it ran for few hours, sometimes it ran for few minutes. Is this a potential bug?

As this buildpack only installs the binary, this should be a bug of your script or casperjs. The process might hit the CPU/memory limit of Heroku and get killed.

Is your script running correctly in a local environment?

You can also manually install casperjs and phantomjs into any Heroku instance and try the script out. If it can be fixed by the latest version of casperjs and phantomjs, I can do the update. If the issue can be reproduced, ask about it on Heroku Forums.

Yes, my script loads correctly in local environment; it runs for 3 days in local and complete without any issues. How can I review whether if I reach Heroku's resource limit ?

Will try to manually install the CasperJS & PhantomJS on Heroku and retry. Thanks for your help.

For that you have to consult Heroku forum. Hope it helps.
