We have recently noticed that our Tomcat installation is writing incorrect
data to the localhost_access_log. It seems to be writing cached data of a
previous request for some or all of the fields. For example, sometimes the
jsessionid of another IP/client is written in the logs of having made a
request for a page. There are other times where the request came from one
computer, but is logged with the IP and sessionid of another computer. I
have included a sample of the access log that shows what I mean.
So far we have upgraded to the newest version of Tomcat (8.5.5) and added
RECYCLE_FACADES=true to our catalina.properties file. We also see the
same behavior from inside our application using getRemoteAddr(). At this
point I am not really sure how to proceed as google doesn't return anything
about a problem like this. Any suggestions would be appreciated.
