Everytime my embedded virtual tomcat server is ran (spring boot) it creates a directory structure in /tmp/ that is named tomcat.##########################.8080 (I am guessing 8080 is for port or something but the 8080 is consistent). This structure does not take up much space alone but after running the tomcat server often over time this can fill up. Can I prevent this from happening as a configurable option?
An example of the path created can look something like:
/tmp/tomcat.1185139485157901.8080/work/Tomcat/localhost/_/
SESSIONS.ser
WEB-INF/ etc. etc. etc.

Unfortunately, both embedded and non-embedded Tomcat needs to have a directory to store temporary files. This is not configurable, however, you can specify the directory in which Tomcat stores these temporary files using setBaseDir.
This should be the first method called public void setBaseDir(String basedir) and if it is not specified in your code it will look for it in
system properties - catalina.base, catalina.home - $HOME/tomcat.$PORT
By knowing the location I recommend writing a simple scheduled script that checks every so often and removes the files under that directory.
