question on setting ulimit on debian

Hi,

I’ve been trying to increase the number of open files for the dovecot user on Debian 9 and have so far, failed! I’ve tried this:

# cat /etc/security/limits.d/limits_dovecot.conf dovecot soft nofile 2048 dovecot hard nofile 8192

# cat /etc/systemd/system/dovecot.service.d/service.conf LimitNOFILE=8192

But to no avail:

# prlimit -p 27208|grep -i nofile NOFILE max number of open files 1024 4096 files

Lost me :( Any ideas?

Thanks,Sophie.
