It works fine most of the time, but if I let it run for around a day, I eventually get this error:  signal  7 : Bus error setindex! at sharedarray-jl:285-jlcall_setindex!_22036 at   unknown line -jl_apply_generic at  ubc cs research tracking-raid julm libraries julia-4.0 julia-e5c6964a49 bin .. lib julia libjulia.so  unknown line    more stuff from my own code   Like I said, the error is somewhat erratic in that this piece of code runs many many times and then suddenly fails.  tkelman The Julia Language member tkelman commented on Feb 19  Can you point us to something reproducible that we would be able to run? Without that I don't think there's enough to go on here yet.  ViralBShah The Julia Language member ViralBShah commented on Feb 21  Cc  amitmurthy  ViralBShah The Julia Language member ViralBShah commented on Feb 21  Definitely need a reproducible test case.  ViralBShah ViralBShah added the parallel label on Feb 21  JaredCrean2 JaredCrean2 commented on Feb 21  I have seen the same thing running a serial code for roughly 9 hours, but I haven't been able to reproduce it with any consistency.  skariel skariel commented on Feb 23  I have a similar thing, I think it happens only when I use very large arrays. Using smaller ones with same code everything is OK. -jltmtz-jltmtz commented on Feb 23  Sorry, I tried but I wasn't able to reproduce.  Should I close this issue or leave it open for others future reference? Currently google returns nothing when one googles this error.  amitmurthy The Julia Language member amitmurthy commented on Feb 23  Since other folks have also reported the same issue, lets leave it open for now.  vtjnash vtjnash added the needs-more-info label on Mar 8 This was referenced on Mar 9 Merged use of finalizers to release remote references shared arrays early.  15436 Open Large number of temporary shared arrays crashes Julia. Need a more aggressive gc?  15415  amitmurthy The Julia Language member amitmurthy commented on Mar 13  This issue appears to the be the same as  15415 . Closing it for now. If on 0.5 please try with calling finalizers to force an early release. If on 0.4 you will need  15441 merged to do the same.  Please reopen if you have a reproducible test case different from  15415  amitmurthy amitmurthy closed this on Mar 13
