zend cache issues

Hi, sometimes there occurs an error but I cannot make out why this is happening. The error is:

Uncaught PHP Exception RuntimeException: "SplFileInfo::getMTime(): stat failed for /tmp/Shariff-a1/Shariff-c6fb9831d0be14eb5a6e65db8002dad1.dat" at /path/to/project/vendor/zendframework/zend-cache/src/Storage/Adapter/Filesystem.php line 153 {"exception":"[object](RuntimeException%28code: 0%29: SplFileInfo::getMTime%28%29: stat failed for /tmp/Shariff-a1/Shariff-c6fb9831d0be14eb5a6e65db8002dad1.dat at /path/to/project/vendor/zendframework/zend-cache/src/Storage/Adapter/Filesystem.php:153)"} []

Do you have any clue? Thank you in advance!
