[TYPO3-english] Migration 4.6 to 6.2: error "Could not acquire lock for ClassLoader cache creation"

Hi again,

Wrong diagnostic.

My Install Tool worked for a while flawlessly, I could perform some 
operations. Then I tried to regenerated the encryption and it failed 
again. Since then I can't get it to run again. A backtrace in the 
ClassLoader spits out the following:


#0  TYPO3\CMS\Core\Core\ClassLoader->acquireLock() called at

Looking at "typo3temp/Cache/Data/cache_classes" I can see already 26 
cache files. Why would this one fail (note that it does not exist yet)?

The disk is not full, there are some 570GB to go...

Any hint what is happening?

Cheers
