Hi Marcel & Mason, Thanks for the assistance to identify the problem. BTW I’m running Ubuntu 16.04 LTS and installed from packages lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 16.04.3 LTS Release: 16.04 Codename: xenial My local fix for this was: 1) Locate the latest version of koha-functions.sh in Git and copied the missing function run_safe_xmlstarlet https://github.com/Koha-Community/Koha/blob/master/debian/scripts/koha-funct... <https://github.com/Koha-Community/Koha/blob/master/debian/scripts/koha-functions.sh> Here is the body of the missing function in case others need to do the same manual patch run_safe_xmlstarlet() { # When a bash script sets -e (errexit), calling xmlstarlet on an # unexisting key would halt the script. This is resolved by calling # this function in a subshell. It will always returns true, while not # affecting the exec env of the caller. (Otherwise, errexit is cleared.) local instancename=$1 local myexpr=$2 set +e; # stay on the safe side echo $(xmlstarlet sel -t -v "yazgfs/config/$myexpr" /etc/koha/sites/$instancename/koha-conf.xml) return 0 } 2) Edited my local copy of koha-functions.sh: sudo vi /usr/share/koha/bin/koha-functions.sh 3) Appended the function run_safe_xmlstarlet to the end of the file and save 4) Re-enabled plack on all instance and restarted the VPS. This seems to work ok for me in that performance is back to where it was and things seem to be running ok… HTH Alex Shepherd

Mason, You are missing something here in 16.05.19. git grep run_safe_xmlstarlet debian/scripts/koha-plack: PLACK_MAX_REQUESTS=$(run_safe_xmlstarlet $instancename plack_max_requests) debian/scripts/koha-plack: PLACK_WORKERS=$(run_safe_xmlstarlet $instancename plack_workers) The routine should be in koha-functions.sh.

This is a routine in debian/scripts/koha-functions.sh Make sure that you have the correct koha-functions.sh in the right location (usr/share/koha/bin)

Hi Team,

I’ve just done an upgrade to my koha systems to 16.05.19.000, but after the upgrade I was getting “Service Unavailable” messages.

I tracked it back to plack not starting.

For now I’ve disabled plack on all the instances and restarted apache and they’re all working again, but performance will be less…

Here is the error I see:

root@koha:/usr/sbin# koha-plack --start bbs /usr/sbin/koha-plack: line 77: run_safe_xmlstarlet: command not found

Any suggestions?

Regards

Alex Shepherd
