Hi,
I have a local RPM repository that syncs from an internet mirror of the
CentOS 7.3 updates repository. 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:
$ 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
This command may be exited via ctrl+c without affecting the request.
[-]
Running...
An internal error occurred on the Pulp server:
RequestException: GET request on
/pulp/api/v2/tasks/776894cc-b524-4f2f-bd30-c8c4d8237c31/ failed with 500 -
[Errno 12] Cannot allocate memory
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
https://pulp.plan.io/issues/1779, 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.
Thanks,
