[TYPO3-caretaker] Chart - switch between dates

[Nina]

 Hi,

 since a while you can switch between chart dates.
 Like 1 hour, 3 hours, 24 hours, 3 days, 7 days....
 That is realy nice and works fine. Till 7 days.
 After that i get an white page. The PHP Error log says:
 PHP Fatal error: Allowed memory size of 33554432 bytes exhausted (tried 
 to allocate 4104 bytes) in 
 /htdocs/typo3conf/ext/caretaker/classes/repositories/class.tx_caretaker_TestResultRepository.php 
 on line 252

 Has someone of you the same experience?

 Greetings
 Nina
