"failed to serialize the map/cached read - read request too big" (Map Editor problems)

[digitalxak]

I have been trying to help a user recover from a consistent error when using the map editor, recently they have been getting the message "failed to serialize the map" when saving.

I've been on the SCS Forums, in a few Discord servers and running out of places to ask now. I have looked for solutions but cannot find a solid one.

Here's the last editor.log they sent:

A very common error occuring in this log is: <ERROR> [fs] cached read - read request too big. I have no idea what this refers too, it's the first time I've seen it.

They have tried:

Reinstalling the game.
Verifying the game files.
Deleting the ATS Documents folder to generate a new one.
Deleting the aforementioned .aux files and rebuilding the map.
Rebuilding the map generally.

May be more but I have forgotten.

Regarding the sign errors, those are my signs but we're trying to sort out def files too. The signs work it's just def files atm.

At first glance I would say that you don't need any of the following parameters while using the map editor:

• -mm_pool_size 8000 -mm_max_resource_size 32 -mm_max_tmp_buffers_size 1000

Because it seems you are requesting an 8GB loading buffer but you had a little more than 6GB of free RAM when the editor was started.

This isn't mine it's for someoneon else. I'll pass that on thanks, They use those parameters that I suggested in the wrong place.

Edit: They removed that line it's still crashing with the serialize error.

@digitalxak, did you ever get the issue resolved? As I’m having the same problem. Asked on discord and forums but no one ever replies
Thanks
