Webmail warning pops up about connection to server, api log

[deyjvu]

Recently upgraded this site to 11.4.5 and some users are having issues when accessing their folders with webmail. I logged on and experienced it myself. I was opening a folder with about 1000 messages, it only showed some of them and then I hit Send & Receive All a few times then I got a popup that said there was a server connection error with an OK button only, clicked that and it kept popping up every few seconds for a while. I went out of the folder, into an empty folder, back to the original folder and all the items were displayed eventually... took a few minutes to display them all.

In the logs I found this scalix-api.log:

But there was only one of these errors but I saw loads of the popup warning box.

In the scalix.swa.log I get:

Any suggestions what is the issue or anyone else seen this, fixed this?

Check that Postgres is running correctly. If this is not the case, the mobile client will fail completely, so it's easy to test.

Alternatively, you can try to clear the user's IMAP cache as well.
