This issue seems to be duplicate of few others:
- Initial report - client (stack overflow): fixed via
MC-121331 - Initial report - server (watchdog) - server seems to writing logs about overload (`Can't keep up!`), so maybe some IO contention? Does not seem related directly to this
- Later reproductions seem to be duplicates of
MC-45838 MC-130303is symptom ofMC-131019and seems not related to this one
Thank you for your report!

@bemoty Are you sure?
MC-123194is about «/data get»; this bug is about «/data merge».Additional information: this bug causes on a server.
@Bemoty
Its seems /data merge doesn't seem to override the data in signs as it probably should. it just add the data onto the already existing data causing very big nbt data per sign affected. I have a world where the signs updated with that command just get heavier and heavier to render for the engine. causing significant performances issues. I have a video of me removing those 4 signs in my world, which allows my fps to go from around 20 to 400 fps.

and this is still an issue in Minecraft 1.13-pre1
I would say that
MC-123194is the result of problems with this /data merge
