There were multiple issues in retry() in rhel-registration:
- There was no need for it to be recursive (local variables
got overwritten)
- There was no delay between multiple attempts, leading to faster but
more frequent failures.
- The max number of attempts was set too low for some environements.
With this patch, rhel-registration now works more reliably with slow-links
for portal registration and does not attempt to DDos the portal or your
satellite server.
