Issue #4603

Updated by dkliban@redhat.com over 5 years ago

This does not occur 100% of the time, but often enough that it can be reproduced consistently.  

 1) Create an 'on_demand' repository pointing to a RHEL 7 kickstart repository.  
 2) Sync the repository. 
 3) Download the repository 

 <pre> 
 pulp-admin repo download --verify-all --repo-id ks 
 </pre>  

 As the pulp_worker was downloading the file the following was emitted by pulp_streamer: 

 <pre>

 Then the pulp_worker emmits the following:

 ('Received response with content-encoding: gzip, but failed to decode it.', error('Error -3 while decompressing: incorrect header check',)). 

 </pre> 

 I was also able to cause this by simply requesting the initrd.img from the on_demand repository.
