Hi all,
I observed the following warning at squid cache logs:
WARNING! Your cache is running out of filedescriptors
Googling around I tried to increase the default file descriptors of the system (I am runnign Debian9 x64 bit), by setting at /etc/sysctl.conf:
fs.file-max=802762
Restarted system. Still was receiving the warnings.
When checking further I observed that I have the following default limits:
ulimit -a
core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
scheduling priority (-e) 0
file size (blocks, -f) unlimited
pending signals (-i) 15338
max locked memory (kbytes, -l) 64
max memory size (kbytes, -m) unlimited
open files (-n) 1024
pipe size (512 bytes, -p) 8
POSIX message queues (bytes, -q) 819200
real-time priority (-r) 0
stack size (kbytes, -s) 8192
cpu time (seconds, -t) unlimited
max user processes (-u) 15338
virtual memory (kbytes, -v) unlimited
file locks (-x) unlimited
core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
scheduling priority (-e) 0
file size (blocks, -f) unlimited
pending signals (-i) 15338
max locked memory (kbytes, -l) 64
max memory size (kbytes, -m) unlimited
open files (-n) 1024
pipe size (512 bytes, -p) 8
POSIX message queues (bytes, -q) 819200
real-time priority (-r) 0
stack size (kbytes, -s) 8192
cpu time (seconds, -t) unlimited
max user processes (-u) 15338
virtual memory (kbytes, -v) unlimited
file locks (-x) unlimited
Where the "open files" seems to be the related one.
I set also the following at squid conf:
max_filedescriptors 65535
I am running a compiled version 3.5.23.
I am not sure I have done the correct steps or if I need to tweak the ulimits also.
Any experience from your side?
Thanx,
alex
