Folks:
We'd gotten some word that people were experiencing memory problems trying to get into VPhot this afternoon. I logged into the server and found that 90% of the memory was in use. I took the unusual step of rebooting the VPhot server. We're now down to 50% memory in use and both the FTP and image processing services are running.
There was nothing in the incoming directory for image processing when I rebooted the system.
I logged in to my VPhot account with no issue, so I'm hoping that will alleviate the problem.

Hi Doc
Do you have any idea what all this stuff in memory was? It was taking half the capacity! Did you reboot VPHOT this morning?

Any chance VPhot has memory leaks? This is not uncommon even with the best of intentions/effort.
Has a tool like Valgrind or the Microsoft equivalent been run against the C++ (as I recall) code?
Just a thought.
Then again, Doc's comment suggests that such high memory usage is unusual, and I also don't know over what period of time that occurred (getting to 90%).
