Tomcat has been running for a period of time, but it has not been reported correctly, but it cannot be accessed.

tomcat can be accessed normally at the beginning, but after a week or two of operation, it cannot be accessed normally, and it does not report an error, but it just cannot be accessed, which is very strange.
jdk and tomcat are both 32-bit, is that the reason


try jstack to type out the information of the call stack of tomcat when it cannot be used.
