I’m having issues with a spark client which when trying to open a chat window the program freezes, and the CPU usage by spark goes to 30%, e the only way to interrupt this is killing the process by task manager. It occurs only for this particular user (user 1) trying to chat with another particular user (user 2). Other users in the same machine can chat with user 2, and in another machines they can talk with user 2 as well. We already exclude/include the user 1, change the work group and we are still facing the issue.
Does someone already have similar issues ou have an idea of how to troubleshoot this?
