For some long-lasting queries, a MariaDB server can send progress reports back to the client. This behavior is documented here. I noticed the kernel is not properly formatting these progress reports for LOAD DATA INFILE statements, but as you can see in the previous link, there are other statements too that can issue such report messages.
To fix this problem, we should first investigate how easy it is to display the reports nicely based on how predictable the report content is or just disable progress reporting for the active client connection that the kernel uses.
