Dear Friends, It seems that Zebra does not work and search not possible. I found this problem visible with Koha 17.05.x and 17.11.x. My OS is Ubuntu 16.04. Here is the Zebra error log, 20171230 19:30:00 library-koha-zebra: client (pid 9959) killed by signal 15, stopping 20171231 10:15:35 library-koha-zebra: client (pid 1121) killed by signal 15, stopping Regards, -- Vimal Kumar V.
