Warning: fd limit is lower than required under max. load

exim stopped transporting emails

in logfile i get:

Warning: fd limit (ulimit -n) is lower than required under max. load (1024 < 6500), because of default_client_limit

please help asap as this is on a large server and no emails are beeing delivered anymore!!!

running
CLOUDLINUX 7.4 standard [server] v66.0.23
with ConfigServer MailScanner

 

[zye]

[email protected] [/] ulimit -n 922222

did the trick
restart exim - no more error

but again no emails were transported

as mailscanner service was stopped - restarted mailscanner now it works.

how can i set the ulimit to a fixed size - so in case of reboot this wont happen again?

sysctl -a | grep fs.file-max
fs.file-max = 13055535

more /proc/sys/fs/file-nr
135168 0 13055535

lsof | wc -l
6179726

Hello,

The following post offers a manual workaround you may find helpful (it involves changing the file on a regular basis through a cron job):

bash: fork: Resource temporarily unavailable

Thank you.
