Много segfaults и glibc тоже обнаружил ошибки

в моем apache error.log много ошибок segfault:

[core:notice] [pid 16753] AH00052: child pid 4861 exit signal Segmentation fault (11)

А также некоторые glibc обнаруживали ошибки каждые 10 часов или около того:

*** glibc detected *** /usr/sbin/httpd: malloc(): corrupted unsorted chunks 2: 0x00007fcfcde5fd80 ***
