finished background tasks keep piling up (see screenshot). They are not cancelable nor do they vanish. Eventually I have to restart IU9 because memory limit has been reached. I have been removing the ...system/* files several times to no avail except that initially it seems to works and then eventually this behaviour begins.
Attaching log, thread dumps and a screenshot.
Anyone with the same problem? And maybe a solution?
Also after installing I wanted to revert and found that of my 11 modules only 5 got their iml files saved in 'projectFilesBackup'.
