What is the setting for unpackWARs for Host?
Running directly from a WAR (with unpackWARs="false" file will impact
performance. It looks as if something is unpacking the WAR to the temp
directory.
Tomcat does provide the org.apache.catalina.webresources.ExtractingRoot
resources implementation to help alleviate performance issues in this
case but that should only extract the JARs in WEB-INF/lib and location
they are extracted to should be under the work directory and include
"application-jars" in the path.
Maybe some custom "unpack to temp" code?

Hi Folks
Sometimes we get strange errors after deployments to our test server. We just
"solved" some weirdness by manually cleaning out the TC temp folder(s) - again.
Googling confirms what I thought about the TC work versus temp folder:
* "work stores compiled JSPs and other assets".
* "temp is used to store files created using the Java File API for creating
temporary files".
Looking in our TC temp folder, I see subfolders that match all the webapps
(some names changed to protect the not-so-innocent):
* 0-app1
* 1-app2
* 2-app3
* 3-app4
* 4-docs
* 5-manager
* 6-trap
Looking in a subfolder, like temp/3-app4, it appears to be an exact copy of
everything in the webapps/app4 folder, which is just the extracted app4.war
file. (The webapps folder has a copy of app4.war.) The temp/app4 folder does
not seem to contain temporary files, like output files for Excel reports, etc.
Same for the other subfolders. Is that normal?
Some technical specifics:
* TC 8.5.63
* Java 1.8.0_291
* AWS EC2 instance.
* Windows Server 2016.
* Instance started as Windows Service.
* -Dcatalina.home=D:\Tomcat8_1
* -Dcatalina.base=D:\Tomcat8_1
* -Djava.io.tmpdir=D:\Tomcat8_1\temp
* There are other TC instances on the same server.
* Each TC instance has multiple apps.
I see references to the temp folder in tomcat8-stdout.x.log Below are some
excerpts. Why is it trying to access files in the temp subfolder instead of
the webapps subfolder? (Looks like I have some app debugging to do?)
