Symfony 4 crashes when overwriting cache - what could be wrong?

Question

symfony

Colleagues, tell me, who faced the following problem in Symfony 4:
I go on the front 1, the request fulfills normally.
The second request crashes the whole application with an error

AH00052: child pid 18409 exit signal Segmentation fault

For a long time I puzzled over what was the matter, such a moment turned out.
If each time you clean the cache folder (stupidly delete files), then 1 request will be processed, after which the cache will be written and everything will fall again with the same error.
I sinned on the wrong permissions on the file, set
www-data: www-data and recursively access permissions to all 777
As a result, the error persisted, and I don’t know what else to do?
Who faced this?

• Symfony 4.1.8
  
• PHP 7.2.13-1+ubuntu16.04.1+deb.sury.org+1
