Re: Frequent Out of Memory for service(config)

2019-06-05 Thread Root Kev via dovecot

Hello Aki + group.

The following is the latest dump output that I have. Does this give any
indication of what is wrong?  I am not sure what this is really showing
me...

Fwd: Potfix+Dovecot with dsync replication problem

2019-06-05 Thread Zeljko Dokman via dovecot

Hi,
Any ideas?

Regards

To: 


Hi all,

I am still struggling with this issue.
I scraped my previous configuration and started from beginning.
Thanks to Aki Tuomi and his suggestion I changed the users in my
configurations from vmail --> root and that helped.
Now I have a working replication but with some problems and strange
behavior.
Replication works only when I manually execute a command:

"doveadm sync -A tcp:secundary:server:12345"

Automatic fast and full sync do not work:

doveadm replicator status "*"
username
 priority fast sync full sync success sync failed
zdokman
none 01:46:14  01:46:14  01:46:14 -

doveadm replicator status
Queued 'sync' requests0
Queued 'high' requests0
Queued 'low' requests 0
Queued 'failed' requests  0
Queued 'full resync' requests 0
Waiting 'failed' requests 0
Total number of known users   1

doveadm replicator dsync-status
username
  type status

 -Not connected

maillog has no error entries.
my conf files are attached.

I don't understand why is this happening and how to fix it, any help is
much appreciated.

Best regards,
