[j-nsp] MX-series: SHEAF: possible leak ...

Hi!

Since yesterday one of our MX-series routers started logging
next messages: 

 fpc3 SHEAF: possible leak, ID 5 (packet(600)) (10563/512/1024) 
 Stats bucket for jtree app NH negative..

(both are logged by fpc3, another fpc's not affected), and after some 
googling I started worrying, because first message (SHEAF leak) is only 
mentioned in j-nsp some years ago in context of PFE memory leak that can 
stop your router forwarding (PSN-2004-06-009), and the second is cosmetic 
bug closed in PR/400917, concerning PFE memory leak too. 

So, the question is: do you think that fpc reload may help with 
this issue or i should plan JunOS upgrade in next maintenance 
window ? (now this router running JunOS 8.4R4.2 that is EOE/EOL 
anyway). 

PS: messages starter right after provisioning another client's
interface, nothing special: 

cvs diff -u -D '2009-08-27 13:00' -D '2009-08-27 14:00' rt077-201

+            }
+        }
