Hello list,
'open()' for creating file sometimes returns an error:
couldn't open "myfile.txt": resource temporarily unavailable
either in background process or interactively (ex: in Emacs when
trying to save a file).
system: Debian 8.5
with kernel: linux-image-3.16.0-4-amd64
and systemd 215-17+deb8u4
Is that concerned with some imposed limits on the kernel resources ?
Following comprehensible suggestions about checking/changing such limits
from here:
http://unix.stackexchange.com/questions/253903/creating-threads-fails-with-resource-temporarily-\
unavailable-with-4-3-kernel
I checked my circumstances.
me:~$ cat /proc/sys/kernel/threads-max
96126
me:~$ 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) 48063
max locked memory (kbytes, -l) 64
max memory size (kbytes, -m) unlimited
open files (-n) 65536
pipe size (512 bytes, -p) 8
POSIX message queues (bytes, -q) 819200
real-time priority (-r) 0
stack size (kbytes, -s) 32768
cpu time (seconds, -t) unlimited
max user processes (-u) 48063
virtual memory (kbytes, -v) unlimited
file locks (-x) unlimited
me:~$ ls -1d /proc/*/task/* | wc -l
618
I thought the most important - the limit on open files:
me:~$ ulimit -n
65536
But in use there are:
jeder@mhfpklytstime:~$ lsof | wc -l
26117
So those seemingly reasonable suggestions gave me nothing.
It is quite upsetting too that
neither the journal nor /var/log/syslog even mentioned the errors.
Am I missing something basic ?
Thanks,
Andrey
