    <p>I have a python script that runs another python script. that 'other script' (script being run) takes ~ 45[min] to complete.</p> <p>When the 'execution' script is run from Ubuntu's shell, it all works perfectly. </p> <p>I added an entry to cron to run the 'execution' python script. It seems to run at first, but the program is terminated after a few seconds:</p> <hr> <pre><code>user@internet:~/REMOTE_CONTROL$ ps aux | grep python user 1603 0.0 1.4 31504 15184 ?

I tried to replace the script that is being triggered by the 'execution' script, and have it call a simple script that just does the following:</p> <pre><code>while(1): ....print "hi" </code></pre> <p>and it still does not work.</p> <p>Any ideas? thanks.</p> <p>(I am using Ubuntu 10.04 LTS)</p>

    1. COCan you post your python script and the cron file here? It'll be more clear in that way

    3. COAnd make sure that (a) either your cron entry invokes `python` or there is a correct shebang, and (b) the permissions are right. You could also try using `logging` to try to get it to explain what's wrong.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
