[logback-user] Logback stopped writing

[Jenny]

Hi,
 
When my disk reached full capacity, logback stopped writing - this is the expected behaviour. 
 
However my question is when I free up some space on my disk (down to 10% usage), Logback still doesn't write. I need to restart my application in order for logback to start writing again. I want to understand why logback doesn't continue writing when disk has free space again?
 
thanks in advance
