Uwe L. Korn commented on ARROW-1282:
------------------------------------
Current state: It does not seem like large reallocations are a problem but
rather certain sequences. I have now a reproducible environment with
{{jemalloc==4.5.0}} where I can reproduce the hangs. The stacktrace is similar
to that of [~jeffknupp] for the jemalloc part but different for the Arrow
trace. So this points to a jemalloc issue and not in the Arrow codebase.

> Large memory reallocation by Arrow causes hang in jemalloc
> ----------------------------------------------------------
>
> Key: ARROW-1282
> URL: https://issues.apache.org/jira/browse/ARROW-1282
> Project: Apache Arrow
> Issue Type: Bug
> Components: C++
> Reporter: Jeff Knupp
> Assignee: Uwe L. Korn
> Fix For: 0.7.0
>
>
> When reallocating a large amount of memory, Arrow is either triggering a bug
> in jemalloc or has a bug itself in the memory manager (many different
> applications reporting same issue but not clear from jemalloc issue
> description if they're sure it's in jemalloc or caused by other issues like
> using multiple memory allocation libraries in the same process, multithreaded
> access, etc).
> Link to stack trace is here:
> https://gist.github.com/jeffknupp/73879feacf9c560afd4f1a20213dc6ef
> Link to issue in jemalloc GitHub is here:
> https://github.com/jemalloc/jemalloc/issues/802
> Originally observed in redis, discussed with jemalloc maintainer here:
> https://github.com/antirez/redis/issues/3799
> *This is entirely reproducible on Ubuntu 16.04 xenial, which uses version
> 3.6.0 according to `apt` metadata.*
