after a debian update (incl. clamav) and reboot today, the clamav-milter does not seem to start properly. I started the clamav daemon manually after the system reboot, seems to be running but somewhere it seems that something has changed in the start configurations.

Code

currently dovecot seems to be producing a heavy load ... too many connections and processes

is there a recommendation how to optimize it f.ex. lowering imap_hibernate_timeout

which files do I have to edit?

I'm not really an expert with dovecot configuration.

it seems 2 ssl certs where not proper deleted when deleting a domain in table ssl-certs, now it works.

Quote from Nuxwin

Google is your best friend

https://askubuntu.com/question…a-hash-sum-mismatch-error

You were right, thanks Nuxwin!

Code

sudo rm -rf /var/lib/apt/lists/*
sudo apt-get update

I was a little worried about the hash mismatch because of the prior key change, so my first thought was a serious problem with the package sources

Something seems to have gone wrong w/ sury.org ... it worked until this morning and now I get many checksum errors for sury.org packages:

is this archive already deactivated or can I add a new key and continue w/ the sury updates ...

or should these sources be removed completely right now?

Code

hmm, now I have set to 500 ... but default_process_limit still shows 100

dovecot status shows:

Main PID: 27789 (dovecot)
Tasks: 200 (limit: 4915)

can I use following command to get the default_process_limit?

Code

doveconf -d | grep default_process_limit

fulltilt · Mar 13th 2019

thanks I have changed and added the part & restarted dovecot but it still shows 100 for:

Code

default_process_limit

Code

doveconf -d | grep default_process_limit
default_process_limit = 100

How can I allow (raise) more than 100 dovecot processes?

I have about 2-3 dovecot restarts per hour ...

I have already tried some settings but it does not change anything:

Code

nano /etc/dovecot/conf.d/10-master.conf
service imap-login {
inet_listener imap {
process_limit = 500
process_min_avail = 2
#port = 143
}
nano /etc/dovecot/conf.d/10-master.conf
default_client_limit
nano /etc/dovecot/dovecot.conf
search
service auth {
add
client_limit = 500
service auth {
client_limit = 500
