Priority: medium
Bug ID: 56963
Assignee: libreoffice-bugs@lists.freedesktop.org
Summary: Stability degrades with large document
Severity: major
Classification: Unclassified
OS: Mac OS X (All)
Reporter: wa4...@yahoo.com
Hardware: x86 (IA32)
Status: UNCONFIRMED
Version: 3.6.3.2 release
Component: Writer
Product: LibreOffice
I have a rather large document (270+ pages) that has been years in development.
It has tons of footnotes, text boxes, and inserted images, both local images
and links. The ODT file is about 94 MB. I have experienced problems for some
time, but they are intermittent, come and go, and have mostly been merely an
annoyance. However, as the document continues to grow they have become more
and more severe. The problem appears in several recent version of LibreOffice,
as well as OpenOffice and appears on both Mac and PC.
I spent some time with xmllint dissecting the document for errors that might
contribute to the issue, finding no problems, no errors. I have also
experimented with splitting the document into a master document with various
sub-documents, but similar problems still dog my work, and the master/sub
document configuration gives me formatting issues that I have not been able to
overcome as yet, but that's another discussion.
The primary symptom is that writer suddenly becomes unresponsive. This seems
to coincide with any operation that might cause a repagination of the entire
document. Usually, hitting Tools|Update|Update All will provoke the issue
about 90% of the time, but then other times the update occurs without problems.
Attempting to export as PDF also often does so. Lately it has been crashing
on a file|save operation, which is REALLY annoying. I have left it sitting at
times for hours, hoping it might recover, but it does not, the only recovery
being to force a close and then reopen and recover the document. Usually this
means recent changes are lost, which is very annoying.
Occasionally, rather than simply lock up and become totally unresponsive,
writer just quits unexpectedly. Again, recent changes are usually lost.
A few times I have simply opened the document, and then had to leave my desk
for a time. Without my ever touching a keystroke after opening the document, I
find it crashed when I return. I believe it will eventually crash if simply
left alone.
I need help in getting to the bottom of the trouble. There are two aspects.
First determine precisely what it is about this document that provokes the
misbehavior. Perhaps there are XML errors that I have missed when looking at
it with xmllint. Any advice on what to look for, how to use xmllint to best
troubleshoot, or recommendation for a better tool is most welcome. I am
however inclined to believe it is simply the sheer size of the document, along
with the number of insertions.
Secondly, even if the problem is due to document errors, clearly LibreOffice is
not dealing well with the errors. So if we can better quantify what is going
wrong, perhaps specific bug reports can address where Writer is going "off the
rails" when faced with a troublesome document.
I would like to volunteer my system (via remote access) or my document, or both
to anyone from the developer community who is interested in taking a closer
look. I could obfuscate the document and post it somewhere, but as I cannot
really edit it effectively any more that would be difficult. On the other
hand, there is nothing particularly secret about it, so I would trust giving it
to a single developer who would promise not to disseminate it. I can place it
on Dropbox, or Google Drive and send a link via email to someone interested in
troubleshooting. I wouldn't want it widely shared, as I would hope to finish
it before letting it out into the wild, but there is nothing that is really
secret.
I searched the online bug reports, and do not see anything that really seems to
be a duplicate. However #56528 does seem somewhat similar, thus might have a
common root-cause of the failure.
If a developer would like to take a look and try and get to the bottom of the
issue, feel free to email wa4...@yahoo.com.
Regards,
Nathan
I am presently using Version 3.6.3.2 (Build ID: 58f22d5) on an iMac under Snow
Leopard (OS X 10.6.8 ) with 4 GB memory. Behavior is not limited to this
configuration or version.
