This might be caused by the page file being too small, and or because of a memory leak in the software. I don’t know of a leak, but we have to always consider the possibility. The memory leak situation can sometimes be identified when it is related to a linear increase in the virtual size of the Linux process correlated somehow to time or client initiated activity. The gateway does use free lists so its virtual size will remain at the high water mark of memory usage initiated by client load.
