missing text in tmp_content con files

[webfarm]

I have a customer who is having a problem with text entered in the text editor not showing up on the website.
The problem is random, and I've only been able to duplicate it once and not since.

The problem is she enters text into the text editor and saves, the text does not show up on the website. If she re-opens the page in sohoadmin the text is there.
I've found that the text is showing up in the .regen page for the file but not in the .con file in tmp_content.
If I re-save the page in sohoadmin it work fine.

Any ideas why saving a page would write to .regen but not to .con?
How are the .con pages generated? Does pgm-realtime_builder generate them off of the regen file or are both .con and .regen written at the same time.

The customer is using 4.9 r36 but the problem was present in 4.8 as well.
She has tried different browsers with the same results.

Hmm. That's an odd one. The .con and .regen file get written at the same time by this file...

sohoadmin/program/modules/page_editor/save_page.php

To me the fact that this isn't consistently duplicate-able means that there's probably something about the page content on those pages that's messing things up...but that could be a lot of things.

So to make sure I understand: When this problem happens, the page will not save ever, right? As in, it's not like this just happens once then the next time you hit Save Page it's all good, right? What I'm trying to determine is whether the issues is duplicate-able consistently in context of the particular page that's not working.

Hi Mike,

Only the customer has been able to produce this problem, the two times I've actually seen the page content missing from her site but still present in the page editor, re-saving the page has fixed the problem.
The impression that we get is that sometimes resaving the page fixes it and some time it doesn't. Unfortunately the customer isn't very good at giving technical descriptions of the problem.
I'll have a trawl through the error logs and see if anything relating to save_page.php crops up, it may be something is stuffing out on the server when she is saving pages.

it may be something is stuffing out on the server when she is saving pages.
Yah that would do it. Or maybe even something on her end like if here connection's stalling.

I've asked the customer if re-saving the page fixed the problem when it occurred, the response:

The page saving for missing text I did try alot, I stopped doing this as
every time a text box was changed all text disappeared and would not return.
This was tried on 3 different computers. It seems to be fine now, I will
keep my fingures crossed.
