Thanks Chris, I guess you're right, Tomcat 9 allocates less default memory compared to Tomcat 8; I checked our logs and below are the memory parameters which seem to be passed in,
Tomcat 9 - 14-Apr-2023 02:47:55.567 INFO [main] org.apache.catalina.startup.VersionLoggerListener.log Command line argument: -Xms128m 14-Apr-2023 02:47:55.567 INFO [main] org.apache.catalina.startup.VersionLoggerListener.log Command line argument: -Xmx256m Tomcat 8 - 13-Apr-2023 06:10:01.520 INFO [main] org.apache.catalina.startup.VersionLoggerListener.log Command line argument: -Xms512m 13-Apr-2023 06:10:01.520 INFO [main] org.apache.catalina.startup.VersionLoggerListener.log Command line argument: -Xmx1024m Like you suggested, I updated the configuration using Tomcat9w.exe since we are running Tomcat as a service and it is now working without any errors! I updated the sizes from 128MB and 256MB to 512MB and 1024MB respectively for max and min pool sizes. Thank you very much everyone for your help, I truly appreciate it. I believe we can mark this thread as solved.
