Libreoffice-draw document maximum file size

I’m using LibreOffice Drawing to develop an Embedded Microcontroller Project design specification. I’m inserting screen grabs of sections of technical manuals as I’m designing. I read the only other topic asking about LibreOffice writer file size limit and from there learnt that inserting graphic adds to large file size so linking the insert to a image is preferred. I will look into this method, but I would like to know if what I have read mentioning that 22mb file size limit for writer is also applicable to drawing? The current A0 drawing with 14 pages file size is under 10mb and I’m far from finalizing the document.

I have also searched the Draw-Guide 7.2 for file size limit with no success. I have setup 5 minute auto save intervals.

I find that lately LibreOffice Draw will sometimes freeze if I request a manual save after some editing so I don’t have to wait to shutdown computer or while draw is busy automatically saving and I have pasted of moved objects.

The only solution is to then “Force a quit” as the Wait option sometimes does not seem to eventually get around to actually saving. I have also tried to right click the icon in taskbar and request a new document but that also seems to fail. LibreOffice current installation is
Version: 6.4.7.2
Build ID: 1:6.4.7-0ubuntu0.20.04.4
CPU threads: 4; OS: Linux 5.13; UI render: default; VCL: gtk3;
Locale: en-ZA (en_ZA.UTF-8); UI-Language: en-ZA
Calc: threaded

I just tried closing other applications and documents to see if this would help a “freeze” and it did seem to trigger the saving taskbar to start running and subsequent finishing of the manually requested save in short time period <2seconds.
I monitored the 64 bit AMD computer system’s CPU’s (4 x 4Gig) and Memory (16Gig) noting only one CPU rising up to 90% for 2 seconds then dropping to Idle. Memory has about 2.5Gig allocated of the 16 gig available and the Linux Ubuntu Swap memory is not even registering any required use for the processes running.

Now observed an automatic save while zoomed in to 100% on the A0 document on a intense page and noted a 30second period of one of the four CPU’s running at 100% then drop off after auto save completed.

Observed an manual save while zoomed in to 100% on the A0 document on a intense page and after some editing text and noted another 30second period of one of the four CPU’s running at 100% then drop off after auto save completed.

Lol… now I can’t seem to replicated the freeze… but will monitor if happens again and report findings.

There’s no such limit. It may happen that some files of that size contain something (or in such amounts) that break Writer (possibly on some architectures, or in some versions), but the “there is a file size limit” is not correct (other than ZIP format size limit, which is gigabytes for the ZIP specification used in ODF).

Of course, there might be bugs, that require test documents in respective bug reports, to fix and avoid such seeming limitation.

And indeed, there is a limitation coming from available RAM, which is, again, not a file size limitation, but something coming from combination of document model size in memory and the installed hardware.

Thanks for the info.
