Draft email greatly increases in size when saved.
In my NetZero email account, I keep a draft email where I put in different links, comments, and jokes for later. It has the option for plain text or Rich text.
Once in a while it decides to go wild. It almost doubles in size every time you save it.
When I look at it in the email system, it looks fine.
It takes forever to load, forever to copy, and forever to paste into a word processor.
I finally figured out what it's doing. It takes a single forward slash symbol and multiplies it many thousands of times.
In the email program, it only displays the single forward slash.
It got up to about 51 MB in size before I figured it out. That eats up a lot of memory limit.
I deleted the many thousands of forward slashes and now the file/draft is under 200k bytes.
Copying it into a regular word processor and playing with it was very slow and awkward due to immense file size.
Now it only reboots into safe mode.
