Hello, I need guidance on pinpointing a problem on a machine. The problem was not present in 7.7 and previous versions.
The problem is that the terminal at times is not responding. For example, I simply press uparrow to retrieve the last command, and the terminal sits there unresponsive for enough time to wonder whether the system is broken. This is a machine that has been running for years with the same software and regular updates. What it is that I should be looking for, starting for example with systat? Thank you
