High Memory Usage on Carbonio Community Edition

Hi Everyone, 

I am using the community version of Carbonio Mail with its full features, including chat and video call functionalities. However, we have been facing high memory usage issues. Despite providing the server with sufficient resources (4-core CPU and 24 GB RAM) and having only 20 users, memory consumption is steadily increasing by approximately 1 GB daily. Currently, 13.5 GB of memory is already in use, even though the mail server is not being utilized now.

Using BTOP, I observed that the majority of the memory is being consumed by the Zextras services.

Could you please suggest how we can optimize or resolve this issue to maintain stable memory usage? Your guidance would be greatly appreciated.

Thank you for your support.
