I did some local testing and profiling with VisualVM and it > appears that the authentication log messages are permanently retained in > memory. > > I'm using CAS 5.2.3 deployed in Tomcat. Logging levels are set to WARN for > everything. For my local testing I've configured TGTs to expire after one > minute of inactivity and service tickets expire after 5 seconds. After I > run my local test, wait a few minutes, and then click the "Perform GC" > button in VisualVM to run the garbage collector, it still shows increasing > amounts of used memory, with pretty much all of the memory being strings. > Examining them, they are mostly authentication log messages. For example: > > esi1@SERVICE_TICKET_CREATED@ST-199900-pNLEGxw1equhpUJOnkyLYZYe0f4-HOSTNAME > for https://URL@3/6/18 10:36 AM > ST-199900-pNLEGxw1equhpUJOnkyLYZYe0f4-HOSTNAME for https://URL > SERVICE_TICKET_CREATED > > Those three lines are repeated N times and use up all of the memory.
