Tomcat webapp did not work
Hello,
Last November, my tomcat webapps was suddenly not working. I restarted tomcat service and it's come back to normal state.
Access log returned 400 for request at the time
Time Taken: 0.000 0 10.176.94.121 - - [20/Nov/2019:17:54:32 +0800] "-" 400 -
Time Taken: 0.000 0 10.176.94.121 - - [20/Nov/2019:17:54:32 +0800] "-" 400 -
Time Taken: 0.000 0 10.176.94.121 - - [20/Nov/2019:18:01:45 +0800] "-" 400 -
Time Taken: 0.000 0 10.176.94.121 - - [20/Nov/2019:18:01:45 +0800] "-" 400 -
From Catalina log, before the time that I cannot access webapp, there is some log as below:
Nov 20, 2019 5:54:32 PM org.apache.coyote.http11.AbstractHttp11Processor process
INFO: Error parsing HTTP request header
Note: further occurrences of HTTP header parsing errors will be logged at DEBUG level.

As there is no others error, I can't know why it was not working. Could you please help check if those error can made the tomcat to hang and webapps cannot access?
Thank you very much.
