Tomcat Crashing

[kingoftheworld 10]

Has anyone experienced an issue in ERA 6.4 where tomcat appears to go unresponsive?  I had one of our IS folks update their Kali VM while their network connection was NAT'ed off of their workstation that has ESET on it.  We have muted the machine, but I am attempting to clear out the threats from the console.  If I select one or just a couple to mark as a resolved, the web interface becomes unresponsive until I restart tomcat.
