Calibre throwing a Memory Exception

[Thisiswhatiam]

Hi guys,

When i run the

ebook-convert some.html some.mobi

I get the following exception. It is to be noted that i am calling this using backticks from my perl application.
ebook-convert --help works fine. But when i try to convert it throws the following error.

  Traceback (most recent call last):
  File "site.py", line 58, in main
  File "site-packages/calibre/ebooks/conversion/cli.py", line 307, in main
  File "site-packages/calibre/ebooks/conversion/cli.py", line 260, in create_option_parser

MemoryError

This is weird as i dont know what exacltly is causing the problem. Could someone please help me out.

That's an error that occurs in importing a python stdlib module. You've got something screwy in the environment when launching from perl. Make sure the env vars are all the same as when you are launching from a shell.

I hate to sound stupid but how exactly would i go about comparing the two environment variable as i am running this on a bluehost server?

An echo $PATH from the ssh turned up the following

/usr/local/jdk/bin:/home3/username/perl5/bin:/usr/lib64/qt-3.3/bin:/home3/username/perl5/bin:/ramdisk/php/53/bin:/usr/php/53/usr/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11R6/bin:/home3/username/bin

Thanks for the quick reply!

From the perl script my variables are :

/bin:/usr/bin:/usr/local/bin

[Thisiswhatiam]

Okay. I have the same set of paths in both but still the errors persist.

Environment variables are not limited to PATH. Run

env

The env i printed in perl has a http header while that in my ssh does not. Also i cannot compare the two as there are many titles (MODULEBUILDRC and others) which dont even appear when i run the perl cgi env. Also i noted that in my error log there was a line saying:

(13)Permission denied: access to /bmz_cache/5/somenumber.image.200x150.jpg denied

Could this be an issue which is causing the Memory Error.
