[galaxy-dev] Possible Galaxy memory leak?

Hi all-- Our group is running a local instance of Galaxy on a Linux box. We have been noticing a memory issue, where if we leave the server running for a few days, soon all available memory (~8gb) will be used up to the point where the tools fail because they are unable to allocate new memory. While we haven't done any rigorous testing, this issue seems to be independent of the specific tools we run, and actually seems to still appear if we do not run any tools at all. The process "python" is what is taking up all the memory, and the issue is not instantaneous but happens over time. Restarting the server frees the memory immediately. Is this a known issue? If so, is there a known fix for it? Any insight on this would be much appreciated, as it is complicating our efforts to automate long work-flows. Thank you so much for your time Josh Gross, Western Washington University.
