We have upgraded from Drools 5 -> Drools 6.01 and when repeating the processing in each environment we have very different object counts that is causing memory to run out on Drools 6: Below is an extract from a heap dump In Drools 6 the main objects in the heap are 1: 4378006 700480960 org.drools.core.reteoo.RightTuple Where as in Drools 5 there are way less objects 92: 19022 1826112 org.drools.reteoo.RightTuple Has anyone else had any experience of this issue?

31usd_lng_corp_bnd_cr_bbb_usd_over0y_under5y_2 // rule values at A650, header at A644

That was a useful exercise!!, from a sampled set it looks like the RightTuple instances are coming from a single rule package (nccf). This rule package comes from a large decision table of that is maintained by our business users. This results in a large DRL file being generated containing 2371 rules.  Below I have included some of the rules that were referenced in the data structures, I have also attached the generated DRL file.

Are you able to isolate what the FH’s are referencing, Sorry that should be RT, not FH. RT == RightTuple, FH == FactHandle. that might give us an idea of where to look. If you look RightTuple’s they will have a ‘sink' reference (network node) and that sink will have an ‘associates’ map. That map is the rules that node is part of.

That was a useful exercise!!, from a sampled set it looks like the RightTuple instances are coming from a single rule package (nccf). This rule package comes from a large decision table of that is maintained by our business users. This results in a large DRL file being generated containing 2371 rules.  Below I have included some of the rules that were referenced in the data structures, I have also attached the generated DRL file.

Are you able to isolate what the FH’s are referencing, Sorry that should be RT, not FH. RT == RightTuple, FH == FactHandle. that might give us an idea of where to look. If you look RightTuple’s they will have a ‘sink' reference (network node) and that sink will have an ‘associates’ map. That map is the rules that node is part of.

Afternoon, just seen that the attachment that I sent you has been made available via the drools user forum. Please can this be removed ASAP. This is client information that is not to be made public. Thanks From: Mark Proctor [via Drools] <[hidden email]> To: kellyajp <[hidden email]> Sent: Wednesday, 2 April 2014, 12:41 Subject: Re: Possible memory leak in Drools 6.0.1 not sure why this would have a memory leak, it all looks quite straight forward joins. I assume you are using stateless sessions and inserting just a single Position instance? Is there a different number of RT’s after a single Position insert? A small tip, you don’t need so many patterns. All those constraints can go in a single Pattern.

Afternoon Mark, Looks like making the change you suggested ie not needing so many patterns. All those constraints can go in a single Pattern. has significantly reduced the GC's. We are making the changes to all our rule templates and will rerun. Is there a difference in Drools 6 that would make using separate Patterns such an overhead? Thanks From: Mark Proctor [via Drools] <[hidden email]> To: kellyajp <[hidden email]> Sent: Wednesday, 2 April 2014, 12:41 Subject: Re: Possible memory leak in Drools 6.0.1 not sure why this would have a memory leak, it all looks quite straight forward joins. I assume you are using stateless sessions and inserting just a single Position instance? Is there a different number of RT’s after a single Position insert? A small tip, you don’t need so many patterns. All those constraints can go in a single Pattern.
