Barak Korren updated OVIRT-2252:
--------------------------------
    Description: "One of the tests of the CI mirrors python package is starting 
up an HTTP server on a fixed port number.\r\n\r\nThis can cause an issue if the 
same test is running in parallel on the same machine. This typically cannot be 
an issue on the CI infra because it never runs more then one STDCI thread at a 
time on a given slave.\r\n\r\nThis issue does arise specifically on the s390x 
slave because there the same slave is used both by the staging and the 
production CI systems. In that case the two systems might be trying to run the 
same test at the same time, so this can lead to port allocation 
exceptions.\r\n\r\n\r\n"  (was: One of the tests of the CI mirrors python 
package is starting up an HTTP server on a fixed port number.

This can cause an issue if the same test is running in parallel on the same 
machine. This typically cannot be an issue on the CI infra because it never 
runs more then one STDCI thread at a time on a given slave.

This issue does arise specifically on the s390x slave because there the same 
slave is used both by the staging and the production CI systems. In that case 
the two systems might be trying to run the same test at the same time, so this 
can lead to port allocation exceptions.)
