Koha 3.8.3 on Ubuntu 12.04 LTS server (new install, full upgrade) Everything went well on install. Data from 3.6.1 "converted" to 3.8.3 when I opened the staff-admin page; zebra reindex went well for authorities, but failed for biblios first time around: 14:27:16-19/08 zebraidx(3357) [warn] zebra_lock_create fail fname=/var/lock/koha/zebradb/biblios/norm..LCK [No such file or directory] 14:27:16-19/08 zebraidx(3357) [warn] zebra_lock_create fail fname=/var/lock/koha/zebradb/biblios/shadow..LCK [No such file or directory] 14:27:16-19/08 zebraidx(3357) [fatal] Could not select database biblios errCode=109 but after a reboot, rebuild_zebra.pl -b -r -v -x reported nothing fatal (single warning about a register not found, no details); cron job running normally. But neither OPAC nor staff search functions are operational. The only anomaly that I've found so far is that /etc/init.d/koha-zebra-daemon when run from the command line reports failure at line 73 (and does not create any error logs), but ps aux reports the daemon as running (well, "S+" -- sleep forground.) Anyone got any thoughts please? tnx and br - Paul
