In a situation where var/run/zebradb/bibliosocket or var/run/zebradb/authoritysocket is held open by a zombie process, Starman/Plack will report "oAuth error: Connect failed (10000) unix:/home/jcamins/koha-dev/var/run/zebradb/authoritysocket ZOOM" in the error log, but never return anything, leaving the web browser or proxy spinning.
Does CGI not have this issue? Also, any ideas on how to make zebra go zombie?
I am not sure if this is still valid. There has been no new information provided since 2012. It's unclear how to turn Zebra into a zombie.
