[Glass] Does findAllReferencePathsToObject:maxPaths: in GS 3.3.1 ever end?

[PAUL DEBRUICKER]

Hi - 


In a 7GB GS/64 3.3.1 stone on Ubuntu 16.04 I've had a topaz session running for 7+ hours trying to find the 'printit' result of 


SystemRepository  findAllReferencePathsToObject:  (MyCollection at: 13)  maxPaths: 2


After about 20 minutes it output:

RefPathScan at 01/03/2019 05:37:54 PST
  Starting scan  51.
RefPathScan at 01/03/2019 05:37:57 PST
  End of scan 51.  Current status of sub-scans:

  Search oop #  1 ( 861666305):   ***SCAN COMPLETED***
Search oop is reachable from the following 15 limit oops:
      1  oop=  32961281 (aMetaclass3)
      2  oop=  33115393 (aMetaMCMethodDefinition)
      3  oop=  80039425 (aMetaCPSystem)
      4  oop= 179477249 (aMetaWADispatcher)
      5  oop= 358600193 (aMetaCPInboundEmailServer)
      6  oop= 360980481 (aMetaCPTaskScheduler)
      7  oop= 684421377 (aMetaCPBusinessModel)
      8  oop=1422970369 (aMetaTDTopezServer)
      9  oop=1422970625 (aMetaclass3)
     10  oop=1595670785 (aMetaCPrHelpEntrySystemRepository)
     11  oop=4420608001 (aMetaCPUtilities)
     12  oop=4420608257 (aMetaclass3)
     13  oop=12594921729 (aMetaCPUserModel)
     14  oop=12594936065 (aMetaCPAdministrator)
     15  oop=19393736449 (aMetaCPTwilioHTTPInterface)


and has had one CPU pegged at 100% for the remaining 7 hours.  Scrolling back through the scans show several "scans" with more than a million parent references.  

Is this normal?   Should I expect something different from the #findAllReferencePathsToObject: method by now?  


I'm worried theres a cycle or something else I don't understand because there are roughly of the 13,000 instances of this class 12,000 shouldn't exist....

Thanks for any guidance or ideas you can provide.
