Hangs and errors

[stevenb46]

I have some questions. I've never had ImageMagick hang on me. Is it possible or will it just time out. Is there a way to control its behaviour?

What is the best way to grab errors? Are there a list of errors? I'm looking for reasons for failure to generate a "convert" file. Is there a resource (or webpage(s)) that explains this?

TIA!

I have mostly no idea. But you could put one of the -debug commands in your command line. See
http://www.imagemagick.org/Usage/basics/#controls

My guess would be that your tmp directory may be full.

I'm not sure what you are asking. In the code, exception.h defines the exceptions that can be raised. Bugs sometimes cause IM to get stuck in loops that consume CPU cycles and memory. These bugs get reported and fixed.

When "convert" fails, it should send text to stderr that describes the problem, including the C-function and line number.
