I have been noticing on our largish production deployment of Tomcat that some logs display this issue of being "multiple days behind" in the logging output. We have a 3rd-party vendor application installed on an 8-core server which runs a total of 9 applications in Tomcat, with a typical load of 20-30 concurrent users.

For example, when reviewing a SOAP API log request, I see activity being logged that looks like this:

Notice how the time of logging is 2013-11-25, but the detail being logged says 11/21/2013. I am very unfamiliar with Tomcat and the logging mechanism, but this seems very unusual? Can the logging get backed up in queue that far? Or actual web requests get queued for 4 days before they are actually handled?
