I changed the session-timeout for the CAS webapp to 1 hour and restarted Apache/Tomcat to see if that changes anything. If the issue manifests again, I will surely check the memory and cpu usage using the top command. Rainer, I somewhat doubt that getAllFotosets() is causing the problem. Because I

Rainer, Thanks for looking at those long thread dumps for me!! I am sorry. I did NOT take these dumps at the right time (i.e. when Tomcat was inundated with requests and couldn't cope with the load). After I increased the heap size to 512MB (from 64MB default), I am not getting the OutOfMemoryErr

Andre, Thanks for pointing out the high KeepAliveTimeout value in the config file. I have read the docs and have changed it to 5 seconds (which is the default). I am hoping that Rainer could find out from the thread dump where the requests are getting stuck, so that I can put this issue to bed. T
