Apache reported an error, but there is no solution to the search. I'm here to find the answer.

AH00489: Apache/2.4.33 (Unix) OpenSSL/1.0.2l configured-- resuming
normal operations

AH00094: Command line:"/ www/server/apache/bin/httpd"

AH00493: SIGUSR1 received. Doing graceful restart

AH01873: Init: SessionCache is not configured [hint: SSLSessionCache]

the above four mistakes always occur frequently, and the error rate is very high. Baidu has searched a lot, but it has not been solved. Please give me some advice
