Tomcat starts consuming all memory after login to admin panel?

Question

Java

TomCat 9.02, Java 1.8
Hello everyone, I ran into such a problem: as soon as I enter the web server admin panel at least once (even if I close it later), tom cat starts eating all available memory quite quickly. If you do not go to the admin panel, then the memory consumption with the published application throughout the day is ~ 2.5 giga.
Where to look for the cause of the problem? Disabling logging could lead to this?
