Check Personal Email Accounts not working anymore

[Koos]

Hi,
I have been working with Espo crm for a few weeks. However, since 15 May the email is no longer updated. The cron works fine and gives no errors. In the log see this line always coming back:
[15-May-2019 10:30:18 UTC] PHP Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 4196511 bytes) in /home/dac/ public_html/crm-3/vendor/zbateson/mail-mime-parser/src/Message/MimePart.php on line 449
Anyone have an idea how I can solve this?
thanks

Hello,
please check the system requirements in the Administration -> System Requirements.

Maximus I did that, and all options (success) are green
