In one of the 4.1.2 (AIX) implementations I have been a part of, we saw eWay processes obtain large amounts of memory due to parsing and never 'release' that memory. This started to become a problem over time because there was less and less available memory for new processes to use, so we had to recycle the components from time to time to lower the % of used memory on those machines. As I undersand it, this is the way AIX operates - not necessarily a limitation of eGate.
