“file too large” error message in /var/log/maillog
Mar 19th
I run Postfix as the mail transfer agent (MTA) on my server and saw a bunch of “error writing message: File too large” errors in /var/log/maillog as well as senders getting this bounce message:
I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below. For further assistance, please send mail to postmaster. If you do so, please include this problem report. You can delete your own text from the attached returned message. The mail system <example@example.com>: cannot update mailbox /var/mail/example for user example. error writing message: File too large
Ends up that Postfix has a mailbox_size_limit setting & since I didn’t have that set, it was set to the default 50MB. The user’s mailbox was near that limit so I up’d the default to 150MB in /etc/postfix/main.cf:
mailbox_size_limit = 157286400
then reloaded postfix:
service postfix reload
and all was good again.
Debugging JavaScript in Adobe AIR apps
Mar 16th
Several months back I switched from using Notepad++ to Eclipse-based Aptana Studio to develop an Adobe AIR desktop client for work & have been pretty happy with Aptana other than for the huge amount of memory it gobbles up. Late last week the Adobe AIR Development Plug-In for Aptana came out of beta & is great news for anyone developing HTML/JavaScript-based AIR apps (as opposed to Flash/Flex-based).
One of the drawbacks in developing HTML/JavaScript-based Adobe AIR applications is the lack of debugging tools. It doesn’t help that AIR’s error exception will often output an “undefined at undefined” error message in the system console when a JS error occurs, without any stack trace, leaving you to guess where it actually occurred. This is fine for a small application, but when you have tens of thousands of lines of JavaScript code you’ll often be left banging your head on the desk trying to trace down the error in the code.
This screencast from Aptana better illustrates the new features. Be sure to check it out if you’re using Aptana Studio and/or were looking to give it a try!
