<div dir="ltr">We appear to be encountering an intermittent server issue - that is to say, some of the time the npm request for either a json file or a tarball will terminate prematurely, which we believe is due to a request timeout at the client side. We'll be temporarily switching back to the public registry while we investigate. The patch in question is this one: <span style="line-height:1.5"><a href="https://review.openstack.org/#/c/318875/">https://review.openstack.org/#/c/318875/</a></span><div><span style="line-height:1.5"><br></span></div><div><span style="line-height:1.5">Michael</span></div></div><br><div class="gmail_quote"><div dir="ltr">On Thu, May 19, 2016 at 6:21 AM Michael Krotscheck <<a href="mailto:krotscheck@gmail.com">krotscheck@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Well, my current theory is that npm's default timeout and retries are set too permissively for cold AFS caches (2 retries, 10 second mintimeout, 1 minute maxtimeout). We _just_ landed this patch (<a href="https://review.openstack.org/#/c/318279/" target="_blank">https://review.openstack.org/#/c/318279/</a>) which increases both the # of retries and the timeouts, which would address that issue.<div><br></div><div>We've got two choices- revert the mirror configuration, or wait for this patch to be propagated to our slaves. Both of them will require a dib run, which happens once a day, so neither fix will be available until tomorrow. Frankly, I'd prefer to move forward than back, so I'm going to check in the infra channel to see if we can trigger that run manually.</div></div><div dir="ltr"><div><br></div><div>Michael</div></div><br><div class="gmail_quote"><div dir="ltr">On Thu, May 19, 2016 at 5:41 AM Vitaly Kramskikh <<a href="mailto:vkramskikh@mirantis.com" target="_blank">vkramskikh@mirantis.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div>It seems this issue started to affect us on OpenStack infra about 13 hours ago.
