Thanks Lennon! I enabled and started Plack (with one extra command needed):
- sudo koha-plack --enable library - sudo a2enmod headers proxy_http - sudo koha-plack --start library After doing so I was hoping the problem would be magically* fixed but alas batch check outs still aren't working reliably: - Choose a patron - Switch to batch check out - Paste in 88 barcodes - Click "check out" - Wait over 10 minutes for a "Gateway Timeout: The gateway did not receive a timely response from the upstream server or application." While it was running I ran htop to see if memory or processor was causing a bottleneck but neither processor was maxed out and the RAM was hovering around 1.44G of 3.84G. My plan for tomorrow is to try profiling circulation.pl using Devel::NYTProf ( https://wiki.koha-community.org/wiki/Profiling_with_DevelNYTProf) and see if that gives me any clues.
