[HTCondor-users] ImageSize increase too big

[Henning Fehrmann <henning.fehrmann@xxxxxxxxxx>]

Hi,

we observed an unexplainable jump in the imagesize of an job.


-- Schedd: atlas2.atlas.local : <10.20.30.2:38705?... @ 05/05/18 12:52:07
 ID         OWNER            SUBMITTED     RUN_TIME ST PRI SIZE   CMD
2728869.0   XXXXX         4/28 11:29   7+00:14:54 R  0   9766.0	  XXXXXX 

But it never was using that much memory:

000 (2728869.000.000) 04/28 11:29:25 Job submitted from host: <10.20.30.2:38705?addrs=10.20.30.2-38705+[--1]-38705>

The job still runs on 10.10.9.13 with in the expected memory usage.

The imagesize however is
condor_q 2728869 -l|grep "^Image"
ImageSize = 10000000
ImageSize_RAW = 7522980

Which hasn't been manipulated by the user.

Is this a known issue?

We are running condor 8.6.
Do you need more config or logs?


Cheers,
Henning
