Possible Memmory leak
-
Our Kopano server started to throw bellow error yesterday.
The user vissible error is, that some emails never reach their mailbox till the server is rebooted.When I have just Rebooted the server it uses about 4GB of RAM after a while that increases to >12GB + Swapping. This leads me to the assumption of a memmory leak.

Hi @ana-u,
@ana-u said in Possible Memmory leak:
version 8.7.1
this version is already quite old. can you upgrade to the latest version (customers in UCS can add credentials for our download repository from the app settings) and check if the error persists?
