Make changes to your mpm config in Apache. It sounds like there is increased
traffic. It could be that you reach the max then it holds all those
connections. There are a lot of online resources that have Apache Webserver
recommended mpm settings and models to use for high traffic systems.
Also check with the application devs for any changes that have been made that
might increase this traffic. A database lock means that something is updating
the database while something else needs to update at the same time.

Subject: DB2 database locks [EXTERNAL]
** CAUTION: External message
Hello Team ,
We have been encountered another issue with the Database locks recently ,
yesterday there was been Table locks identified from the Database team , and
after certain period of time we have received the below error on the Apache
logs and we have to restart the tomcat/Apache instances.
: [Mon Oct 17 04:21:04.599196 2022] [mpm_event:error] [pid 10576:tid
140052698470144] AH00484: server reached MaxRequestWorkers setting, consider
raising the MaxRequestWorkers setting
we needed your suggestion as how these errors can cause the Apache to go with
worker exhaustion error.
Apache version - 2.4.25
