A large amount of data being dumped into a computer's logs. Often this data is spurious and of poor quality, and hides the valuable information amongst the crap.
I was running apt-get and my screen was filled with logarrhea. I couldn't even tell if it worked or not.
Not quite diarrhea, and not quite a regular shit. Logarrhea falls somewhere in between the two. A faster wetter shit. Diarrhea with a few logs mixed in.
Are you sick? Do you have a stomach virus?
No I just had a little logarrhea.
