StatusException: ExportChangesICS->InitializeExporter(): Error, mapi_exportchanges_config() failed: 0xFFFFFFFF8004010F

As it turns out, my fix from above is not really fixing it. After a few hours or sometimes days, the behavior appears again - always for the same users.

The really weird thing is that it happens from one moment to the other, without any changes happening. And sometimes the issue disappears the same way on it’s own.

Anybody any ideas what it could be caused by or how it can be fixed permanently?

Kopano Core: 8.7.80
Z-Push: 2.4.5+0-0

Edit: If it helps, I can provide a WBXML log where the issue is happening.

Manfred

Hi kg,

yes, the WBXML log would be helpful.

Manfred

kg

@Manfred Thank you. Sent you the wbxml log in a private message.
Hope this allows us to finf the issue. If you need more info, please let me know.

Manfred

Hi kg,

do you have WBXML log from earlier? According to the log the folder with the issue was successfully synced at 15:15 UTC.

Could you also post z-push-admin output for that device?

z-push-admin -a list -u user -d deviceid

Manfred

kg

Hey.
Sadly I don’t have any wbxml log from earlier. I can remove the device and add it again and then capture a longer one, if that helps.

The z-push-admin output:

Maybe this helps as well: Currently the z-push-top output for the affected user looks like this:

While I’m trying to sync, constantly new gray rows appear…

Alright. I removed the account from the device and then from the server, rebooted the device and created the account again on the device. I sent you that log again as a message.
Looking forward to your analysis.

Thank you.

By “then from the server” do you mean that you removed the device using z-push-admin? If not, please do that before creating the account again.

It looks like you’re trying to sync 1 week back and there are more than 7000 items in the inbox for that time, is it correct? Did you try to reduce the sync window to 3 days or 1 day?

How many users are on the system?

Yes, thats exactly what I did.
It is correct, the device tries to sync one week of emails, but that one week of emails is only ~100 emails (I checked it in the Webapp). The 7000 items is the total number of emails in the inbox which are from May 2017 onwards.

I haven’t tried to reduce the window to less days, but will do so and report back.

There are 14 users on that system: Most of them have a total store size of less than 10MB, 6 of them have a total store size between 200 and 1000MB.
The user that I sent you the log of has a total store size of 400MB.

Thank you

kg

I reduced the sync window on the client to 1 day (the lowest possible one), but the picture is still the same: The same error is reported for every request and the wbxml log looks the same (at least to me) as well.

z-push-admin is still reporting that it tries to sync the whole folder:

Synchronization progress:

Hi kg,

As mapi_exportchanges_config() call is failing, it might be the core or the store issue. Maybe you could try to unhook his store and hook it again.

Also maybe the ICS log in KC would help. In the server.cfg of kopano set
log_level = 0x00200000

If you already have some log_level set, then sum the values (e.g. if log_level is 3, then set it to 0x00200003).

Manfred

I unhooked the store and hooked it in again - no change.
I also enabled the ICS log, which is very verbose. It produces a lot of lines like these:

Anything specific that I can look for in there?

Hi kg,

I’m not very familiar with the internals of the core, so unfortunately I can’t help you with that.

If you have a valid subscription, you can open a support case with Kopano.

Otherwise you can open a thread at https://forum.kopano.io/category/15/kopano-groupware-core section as I’m not sure how often the core devs check posts here.

Manfred

kg

Thank you @Manfred for your help on this one.

I opened a topic in the Kopano Core section. Let’s see, if somebody is able to help me to debug this further.

Banesh

Hi, is the problem already solved? Any information about the root cause? I have exactly the same behavior on my system.

mhoffmann75

Same problem here. On my mailbox it is reproducable with the sent items folder. I removed all but 300 mails and it syncs fine. Putting some older mails into this folder (e.g. 2.500 mails) z-push errors out despite setting timeframe to 1 week, 3 days or even 1 day.

Same seems to be the case for calendar.
Still investigating this.

On my site this is latest z-push with latest kopano core.

kg

I was able to resolve it by replacing the underlying database of the Kopano-Core. We’ve been using a MariaDB Galera Cluster and after replacing it with a single instance of MySql, it started working fine again.

mhoffmann75

Finally it seems that unhooking and hooking the store of the user again solved these kind of error - crossing fingers…

mhoffmann75

Unfortunately after a few days the same problems reoccurred :-(
Yesterday i did move my database from mariadb to mysql which (it seems again) did fix all these kind of errors.
