Hi all,
I got today alert (actually blinking TimeSlider icon) that root FS is
more than 70% in use (that is my setup).
Went to check what occupies so much space, and found:
$ pfexec du -sch /*
...
76G /proc
Correction:
$ 67G /proc/22973
I was confused, so:
$ ps -Zef| grep 22973
global mysql 22973 1 0 Sep 27 ? 419:56
/opt/MySQL/5.7_32/bin/mysqld --user=mysql --datadir=/var/MySQL/data/5.7
--pid-f
Well, that is self compiled 32bit version of MySQL server (we need it
for some reason)...
What is using so much memory (top shows almost nothing)?
After server bouncing, I got 4GB usage for MySQL PID /proc space, which
is normal.
Maybe my compilation leaks memory? Or MySQL setup needs tweak (some tmp
files created in memory)?
I am just curious if someone else spotted similar problem.
Also, I know that I can truss process - but what if that generates
another big file (I cannot seat and watch truss output)?
I probably do not have reason to be worried, but still - between my 1st
and this second mail:
$ du -shc /proc/* | sort -h
...
1,2G /proc/4225
1,5G /proc/4652
2,1G /proc/10220
12G /proc/18087
20G total
$ ps -ef | grep -E "10220|18087"

(please note that MySQL instance is used for some testing)
Regards.
P.S: rpool is installed to 256GB SSD drive, and /opt and /var/MySQL are
located on HD zfs file systems
