Problem with tomcat hanging on Shib 2.4

[C R]

Hi John,

We run IDP on RHEL 6.5 using java-1.7.0-openjdk-devel. Very stable so far.

I have only experienced a tomcat6 "hang" once. The IdP kept working, but
behaved strangely. "Active" logs stayed empty while the messages arrived in
the log files with the date of the day before. Most logins worked as
expected, but a few failed. While debugging, a hup signal let the tomcat
process hang. Tomcat had to be restarted to fix the problem.
