Re: [julia-users] Does Julia 0.5 leak memory?

[K leo]

I ran some more tests with both my original code and some test codes, now 
with the 0.5 release version.  I would conclude that memory is not leaking. 
 The memory usage as reported by top is the actual memory used or having 
been just used.  Although the usage number does not drop after the code 
finishes, it does not further grow with new runs.  Actually with new runs 
the memory usage starts afresh.

It could be that the release version of 0.5 fixes this.  Anyway before any 
further evidence, we can disregard this thread now.

Re: [julia-users] Does Julia 0.5 leak memory?

[Luke Stagner]

In trying to create a reduced test case I figured out the source of my 
memory leak. It wasn't caused by Julia but by an external library I was 
calling (Sundials.jl). Pulling the dev version of Sundials.jl fixed the 
issue for me. 

K Leo, if you are using any external library, that may be the cause of the 
memory leak you are seeing.

In the mean time, I would also appreciate if you can reduce it a
little, especially if you can remove some of the external
dependencies.

I don't have time currently but I'll try to reproduce it in a few days.
What's your versioninfo() and how did you install julia?

Re: [julia-users] Does Julia 0.5 leak memory?

[Yaakov Borstein]

For what it's worth, I have a production system that was developed on 
0.4.6, and started running it today on the 0.5 release.  It retrieves data 
from dozens of API's as JSON, processes and converts them to DataFrames, 
reconverts to JSON, caches the results in Redis.  Sizes range from several 
mb's to 500 mb's.  The routines have been running for several hours, 
allocating and deallocating large chunks of memory for the DataFrames with 
millions of rows and large JSON blobs.  No leaks whatsoever have been 
detected, humming away smoothly with slightly less maximum memory consumed 
and what appears to be faster release (gc()). So my guess is that there is 
likely something else going on with the poster's code example

Re: [julia-users] Does Julia 0.5 leak memory?

[K leo]

@Luke Stagner

Since this appears a problem.  Perhaps you can file an issue with your demo 
code.

Re: [julia-users] Does Julia 0.5 leak memory?

[Luke Stagner]

I actually ran into this issue too. I have a routine that calculates fast 
ion orbits that uses a lot of memory (90%). Here is the code 
 (sorry 
its not very clean).  I tried to run the function `make_distribution_file` 
in a loop in julia but it never released the memory between calls. I tried 
inserting `gc()` manually but that didn't do anything either.

The only package used (at the global level) is DataFrames.  Does that not 
release memory?

Learn to use valgrind -- it is a life skill (like knowing how to do a tax 
return :-P)
http://valgrind.org/

Julia specific instructions are at:
http://docs.julialang.org/en/release-0.5/devdocs/valgrind/

Valgrind's whole purpose is to tell you if a program is leaking memory.
