Hi to all, In the previous month I try to fix the problem of zebraqueue. I find that is too difficult for me. But I find a solution (for my library). Every night I stop the demon zebraqueue and zebreserver for 5 minutes Every sunday I reboot the server. Every month I rebuilt all zebra indexes. Now (on my library) the problem is not present. I have 6000 bib records with 8,000 holdings. My server is linux debian, 1 CPU and 512 MB. Staff work not very much on records and loans (20 transation every day). I find that more RAM I have, less I need to reboot. Probably a more used server needs a reboot every day. The bug to discuss this problem is bug 5165, http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=5165 There is also an other solution by Tomás Cohen Arazi Bye Zeno Tajoli -- Zeno Tajoli CILEA - Segrate (MI) tajoliAT_SPAM_no_prendiATcilea.it (Indirizzo mascherato anti-spam; sostituisci qaunto tra AT con @)
