Description

Looking through the metacat logs, I found a lot of instances where the HzSystemMetadataMap could not load system metadata for particular pids. Most had dryad in the pid (~1200), but another 130 are from elsewhere.

a random sample showed that it couldn't be retrieved via /meta although the pid could be retrieved from the Dryad MN.

This appears to be another type of half-created content on the CN.

rnahf@cn-ucsb-1:~$ grep 'could not load system metadata' /var/metacat/logs/metacat.log | cut -c60- | sort | uniq | grep -v dryad | wc -l
139
