Maximum server connections setting for Akonadi/KMail

[Jure Repinc]

Hi

Recently I started having some problems with Akonadi/KMail (I have version 
23.04.3). I often (about each hour) get this error dialog in KMail saying that 
authentication did not succeed and the server error message that is appended 
is the following:

Login failed, server replied: A000002 NO Too many open connections ( 50 of 50 
for jlp at holodeck1.com )

After I select Retry in the dialog and confirm the password it all sometimes 
continues working fine, but sometimes I don't get any updates for new email 
anymore and I have to restart Akonadi to get it detecting and fetching new 
email again.

The Kolab Now tech support says that there is an Akonadi setting along the 
lines of “Max number of cached server connections” that I should check and 
lower if needed. But I can not find this setting anywhere.

Anyone knows anything about this setting or the problem? 50 open connections 
appears quite high. Are some connections not getting closed? Is this a bug in 
Akonadi I should report?

Thanks in advance
