When I try to create a local copy of this mirror, the celery processes balloon, using all available memory until the job eventually fails as follows: <tt>$ pulp-admin rpm repo copy all --from-repo-id centos-7-updates-x86_64-live --to-repo-id centos-7-updates-x86_64-snapshots-20170216a</tt><tt> </tt><tt>This command may be exited via ctrl+c without affecting the request.</tt><tt> </tt><tt> </tt><tt>[-]</tt><tt> </tt><tt>Running...</tt><tt> </tt><tt>An internal error occurred on the Pulp server:</tt><tt> </tt><tt> </tt><tt>RequestException: GET request on</tt><tt> </tt><tt>/pulp/api/v2/tasks/776894cc-b524-4f2f-bd30-c8c4d8237c31/ failed with 500 -</tt><tt> </tt><tt>[Errno 12] Cannot allocate memory</tt><tt> </tt> As often as not, this renders my Pulp VM inaccessible, requiring a hard reset in order to access it again. This is Pulp 2.12.0 on CentOS 7.2.1511. I presume this is the same issue described in <a class="moz-txt-link-freetext" href="https://pulp.plan.io/issues/1779">https://pulp.plan.io/issues/1779</a>, but given 10 months since that ticket was updated, I figured I'd ask here. I've tried setting PULP_MAX_TASKS_PER_CHILD=2 in /etc/default/pulp_workers, but it doesn't seem to make any difference. Is there a fix or workaround for this problem, or even a means to estimate how much memory a server needs to be able to copy a repo of a given size? This VM has 8GB, and I could add more, but it seems faintly ridiculous that it should be required.
