TYPO3 Core

Hi,

on one of our pages we have a serious Problem after upgrading to 6.2.14 (coming from 6.2.11).
Since that happened, we are not able to delete the cache using the install tool. (Installation -> Important Actions -> Clear all cache)

whenever we try so, we get a message that no data has been sent and the connection is closed.

In the PHP error log we have:

[24-Aug-2015 09:24:54 Europe/Berlin] PHP Warning:  file_put_contents(/home/www/xxxx/html/typo3/typo3temp/Cache/Code/cache_core/55dac6c667f075.31978054.temp): failed to open stream: N

This behaviour is only present on that one page currently. Others running 6.2.14 work fine.

Thanks
