Often, I can see

# Errorstats
syntax_error:4264
some other error ....

errors in running instances but it's impossible to identify the command that triggered it.

I suggest developing a complementary system with a ring buffer that will store last K commands (or command prefixes) that causes
error responses which can be fetched with "DEBUG ERRORS" or something.
