Description of problem: Currently, when we try to register more than 1000 hosts, we start to experience network timeouts, which indeed causes pulp scheduler and resource manager not being able to start properly and hence causes new registrations to fail. The same happens with services like candlepin, which also shows network unreachable. On some investigation, there were some warnings recorded by systemd journal stating: net_ratelimit: 300 callbacks suppressed These problems seem to resolve when we extend the ARP table by setting up the following values in sysctl.conf net.ipv4.neigh.default.gc_thresh1 = 8192 net.ipv4.neigh.default.gc_thresh2 = 16384 net.ipv4.neigh.default.gc_thresh3 = 32768 Can we by default extend the ARP table during the Satellite install? Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:
Thank you for your interest in Satellite 6. We have evaluated this request, and we do not expect this to be implemented in the product in the foreseeable future. We are therefore closing this out as WONTFIX. If you have any concerns about this, please feel free to contact Rich Jerrido or Bryan Kearney. Thank you.
