Re: [HTCondor-users] Memory leak in python binding issue still occurring (Ticket #5727)

[John M Knoeller <johnkn@xxxxxxxxxxx>]

schedd.query and schedd.xquery have completely different implementation - so  there may be a leak with xquery, but it’s not the SAME leak.

Subject: [HTCondor-users] Memory leak in python binding issue still occurring (Ticket #5727)

 

Hi,

 

I am trying to verify ‘memory leak in condor_q client’ issue that was fixed in June 2016 :  Ticket #5727 - https://htcondor-wiki.cs.wisc.edu/index.cgi/tktview?tn=5727

 

But found out that memory leak is still occurring. I have verified that this issue is still occurring on latest stable version 8.6.1 and also on 8.4.11.

 

I used the sample code provided in the ticket to verify the issue:

 

import resource

import htcondor

import gc

schedd = htcondor.Schedd()

while True:

    schedd.xquery()

    # explicitly run the garbage collector to free up mem not leaked

    gc.collect()

    print('mem use: %s (kb)' % resource.getrusage(resource.RUSAGE_SELF).ru_maxrss)

 

 

Can someone please help if I’m missing something or confirm that fix is not available in the latest stable version?
