koha-zebra --stop doesn't work?
Hi all, Is it just me or does "koha-zebra --stop" not actually stop Zebra? David Cook Software Engineer Prosentient Systems 72/330 Wattle St Ultimo, NSW 2007 Australia Office: 02 9212 0899 Online: 02 8005 0595
for me, it successfully stops the zebrasrv process try the following to stop zebraidx koha-indexer --stop $koha_instance On 3/12/20 2:01 pm, dcook@prosentient.com.au wrote:

You don't just violently kill a process. You send it the signal so it closes its open connections, etc. Of course killing it with -9 will yield an empty ps -ef. It would be interesting to see if those defunct processes cleanup after some reasonable time. What OS are you using? (in KTD it would mean what image, default is master-stretch, I use master-buster to develop/QA). El jue, 3 dic 2020 a las 1:34, <dcook@prosentient.com.au> escribió:

Hi Tomas, I think that you misunderstand my email, but that’s my fault for not including enough information. The SIGKILL (ie kill -9) is irrelevant. Please see https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=27140 for much more information. Basically, it boils down to zebrasrv not propagating signals (SIGTERM, SIGKILL, whatever) to its children. (And no the defunct zombie process won’t be cleaned up until its child process exits.) Funny enough, I don’t actually see any way to resolve this situation without patching zebrasrv or using SIGKILL (ie kill -9) to stop all relevant zebrasrv processes.
