Tomcat randomly shutsdown

Question

I ran into a problem from couple weeks with my Tomcat. I deployed my webapp and it's been up and running for some time and one day it suddenly crashed.And I found that this happens when my tomcat server shutdown.

I started browsing Tomcat logs and found below 2 exception many times:

Does this error causes the tomcat to stop its service.

Have you tried another version of Tomcat? It's highly unusual that Tomcat crashes, cause of a 'bad' request... — Ben, Apr 03 '17 at 10:35
@Ben No.But these are the only 2 exceptions that i got from tomcat catalina.out file.Does tomcat stops if some bad request comes many times?? — KJEjava48, Apr 03 '17 at 10:44
What version of Tomcat do you use? There's a version which could be shutdown / crashed with a bad request.. — gusto2, Apr 03 '17 at 11:40
@KJEjava48 No, not in my experiences. Try another tomcat version...Maybe you go out of memory? But this should be also in the log files — Ben, Apr 03 '17 at 11:44
@KJEjava48 It depends on your tomcat logging configuration (./conf/logging.properties), but I think catalina.out is the default. — Ben, Apr 03 '17 at 12:13
