dovecot - Oct 2017 - dovecot: master: Warning: Sent SIGKILL to 100 imap-login processes

Hi,

I am using Dovecot 2.2.32 (dfbe293d4)

I noticed lots of messages like:

dovecot: master: Warning: Sent SIGKILL to 100 imap-login processes

in /var/log/maillog

I commented out "process_limit"


service imap {
# Most of the memory goes to mmap()ing files. You may need to increase this
# limit if you have huge mailboxes.
#vsz_limit = $default_vsz_limit

# Max. number of IMAP processes (connections)
process_limit = 1024
}


but it seems that value doesn't change (still 100).

Any suggestions?

Thank you very much!

So you just commented it out?

so then it?s using the default_process_limit:
# doveconf -d | grep default_process_limit
default_process_limit = 100

which is 100.

Hi,

this is now:

service imap {
# Most of the memory goes to mmap()ing files. You may need to increase this
# limit if you have huge mailboxes.
#vsz_limit = $default_vsz_limit

# Max. number of IMAP processes (connections)
process_limit = 1024
}

This was before:

service imap {
# Most of the memory goes to mmap()ing files. You may need to increase this
# limit if you have huge mailboxes.
#vsz_limit = $default_vsz_limit

# Max. number of IMAP processes (connections)
#process_limit = 1024
}
