comment java program out of memory before reaching xmx
In the /var/log/messages file, you will see OOM killer messages where you can search by the string 'Out of memory'. I would request you to put unsnipped logs pertaining to the OOM messages in the question.

comment Will a vSphere client 5.1 task get cancelled/interrupted if I close out of the client?
@ewwhite Hey man, unrelated question. How can I co-relate the hard drives in vcenter -> settings -> hardware tab to the actual partitions on disk. Do you think this warrants a separate question. I am not much good with vmware.

comment A botnet may be attacking our site right now, how should we respond?
Howdy,Are the requests coming from the same IP address or same subnet. Can you take the IP and perform a reverse DNS lookup to see from where it is originating. You didn't mention which OS. But whatever you are using, how about blacklisting the range of IP addresses that you suspect are attacking?

comment Where do you store shared secrets used in building VMs dynamically (phoenix servers)?
I had a customer with this issue and I resorted to suggesting secret server. Other thing that I have heard good of is Zoho, but I haven't used it though. Have you looked into some open source tools? Also, I upvoted and starred this since I am interested in this.
