FDS in sys top

[onurd0gan]

Hello,

I wonder what does FDS stand for from output of diagnose sys top?

regards,

First, this output is for "diag sys top-summary", not "diag sys top". After some searching on the internet, FDS seems to represent the number of File Descriptors the process(es) is holding. Some articles are saying if the number keeps going up, that's an indication of memory leak.

Not quite a document but some fragments of information + educated guess.

tntf_ftnt is mentioned about FDS counter at Reddit:

Then this showed what FD stands for:

And this explains correlation between the FD count and memory leak:
