Hi, I don't know why your code isn't in the message that went out to the mailing list, but I saw it when I approved the message for the list. Basically you're seeing exactly the issue discussed in the FAQ here:
http://www.jessrules.com/jess/FAQ.shtml#Q12 You've got a couple of rules with patterns like (Method ?m1) (Method ?m2) (Call (something ?m1) (something-else ?m2)) (some-other-test ?m1 ?m2) These patterns first construct partial matches for all pairs of Method facts -- i.e., n^2 pairs, so this uses memory proportional to the square of the number of facts. If you just rearrange it like (Call (something ?m1) (something-else ?m2)) (Method ?m1) (Method ?m2) (some-other-test ?m1 ?m2) then only the relevant pairs will be formed -- presumably a much smaller number. And if you can do something like (Call (something ?m1) (something-else ?m2)) (some-other-test ?m1 ?m2) (Method ?m1) (Method ?m2) then the memory usage will be smaller still. > -----Original Message----- > From: [email protected] > [mailto:[email protected]] On Behalf Of Lucia Masola > Sent: Tuesday, September 29, 2009 10:59 PM > To: jess-users > Subject: JESS: assertion - exception out of memory > > Hi, I'm working in a java applications that has Jess > embedded.
