I experienced a quite similar behaviour on my system. In the end the line

File "/usr/lib/python2.7/site-packages/kopano/ics.py", line 253, in sync

led me to trying to set

enable_enhanced_ics = yes

in server.cfg. On my system the issue was resolved with that step. Why? I don’t have any clue since I was unable to find any closer description of what ICS is.

Would be interested if that resolves the issue on your system, too.

Did some searching again. In fact, ics.py seems to deal with calendar items while the ics parameter in server.cfg is somehow related to caching as far as I understand this. However - setting the mentioned parameter worked for me.

nickh

Unfortunately mine is already set to yes.

Hi @nickh,

did you try to connect to kopano-server via socket?

search.cfg:

server_socket = file:///var/run/kopano/server.sock

nickh

I’ve just tried enabling it and enabling server_pipe_name = /var/run/kopano/server.sock in server.cfg (which I assume had to be done at the same time) and then restarting but it made no difference.

check the rights on var/run/kopano/server.sock
i’ll bet its root:root and your running kopano:kopano

nickh

Everything in /var/run/kopano is kopano:kopano including server.sock and search.sock

Looking at the users I see:

[root@microserver ~]# kopano-cli --list-users
User list for Default (4):
            User           Full Name          Homeserver                                   Store

I have only created 2, test1 and test3. Should the others (especially testusertestuser) be there?

Hi @nickh,

it’s been some time we discussed this topic. Did you solve your issue? If not, you might want to check if max_allowed_packet parameter in mysqld.cnf is increased as supposed in Kopano Wiki.

nickh

Unfortunately mine is already 32M.

genesis74

@nickh, is your kopano-server connecting to the mysql-server via TCP or socket?

nickh

TCP on port 3308 (non-standard) and it is a MariaDB server.

genesis74

@nickh, you could also try to connect to the database server via socket (i.e. in server.cfg: mysql_socket = /var/run/mysqld/mysqld.sock) if both are on the same machine. The combination of rising max_allowed_packet and using the mysql_socket solved the issue on my system (Ubuntu 18.04).

nickh

Brilliant. MariaDB is running in a sandbox on port 3308 and it means its socket file is different from standard (/var/lib/system-mysql/mysql.sock). That sorted it.

Thanks.

nickh

Hmm. It looks like it always happens if you stop/restart kopano-server while kopano-search is running. This means you have to stop kopano-search before stopping kopano-server and start it after starting kopano-server. This is not very workable.

Either the unit files need to be linked by dependencies or the two processes need to be run with a single command. It can be scripted but messy. For a condrestart you’d get something like:

#!/bin/sh

set SEARCH-RESTART=""
systemctl is-active kopano-search -q
if [ $? -eq 0 ]; then
    systemctl stop kopano-search
    set SEARCH-RESTART='yes'
fi
systemctl condrestart kopano-server
if [ -n "$SEARCH-RESTART" ]; then
    systemctl start kopano-search
fi

A restart would be similar.

I always do it that way because if I stop kopano-server I always get errors in search.log like (I cut the long part)

MAPI.Struct.MAPIErrorNotFound: MAPI error 8004010F (MAPI_E_NOT_FOUND)

I did not find any recommendation in the docs but I think kopano-server should always be the last to be stopped and the first to be startet (even though kopano-server logs

[error  ] Error while connecting to search on "file:///var/run/kopano/search.sock"

when kopano-search ist not running. Which is obvious ;-)
