Hints and troubleshooting

Ensure sufficient free disk space

To ensure stable processing, it is recommended to have at least 4 times of the input file size of processed files available for intermediate file system storage (e.g. /tmp on Unix and similar on other systems).

Avoid stopping workflows on Windows

On Windows, you can prevent your workflow from stopping in case of a pdfaPilot CLI crash by setting the following registry entry:

HKEY_LOCAL_MACHINE\
SYSTEM\
CurrentControlSet\
Control\
Windows\
ErrorMode

If ErrorMode is set to "2”, crash dialogs will be suppressed. For further details, see: http://support.microsoft.com/kb/128642/en-us?fr=1

Limiting the maximum memory used by pdfaPilot

Using Linux, you can limit the amount of memory used by a single process by an additional parameter:

--maxmemory=<max. memory in MB>

Processing will stop and result in an error if memory is exceeded.

Performance enhancement

If you want to enhance the performance of your pdfaPilot CLI processes, please keep in mind the following rules:

For embedding missing fonts your system font folder will be scanned unless defined otherwise (see "Font Embedding"). pdfaPilot will create a font cache to improve the performance time, but still it might be useful to remove fonts that are not needed from this directory.

If you are using any font embedding fixups, your system font folder will be scanned unless defined otherwise in the fixup configuration. A font cache will be created to improve the performance time, but still it might be useful to remove fonts that are not needed from this directory.

Creation of XML or PDF reports takes less time than the XSLT option (see "Report types").

Creation of reports takes additional time  even if a profile contains only fixups, an analysis will be executed for gathering report information.

Optimization of needed installation space

To reduce the pace needed by the installation of pdfsPilot, it is possible to delete some subfolders of the CLI component (in subfolder /cli) if their respective functions are not needed in the individual use case.

To avoid processing errors or unexpected behaviour of pdfaPilot any modification should be done well-considered.
