I am hitting almost the same issue as https://groups.google.com/forum/#!topic/puppet-users/9U3es1Z46B0. The difference might be that it occurs randomly here, not consistently. Maybe there''s some corruption with CRL file on puppetca server. Is it ok to simply nil or remove file ''/var/lib/puppet/ca/ca_crl.pem'' on puppetca server? Is it ok to nil or remove inventory.txt file on puppetca server as well? I am not sure what is the correct procedure to get ca_crl.pem file recreated, and I don''t see this is mentioned in any puppet documentation.
