Hi, I was trying to find the string "You must log in using" in Koha, but I didn't find it. Neither in codebase nore translations. Could it be part of a customization that is causing the trouble? You could check IntranetUserJS or HTML customizations containing JavaScript. Or maybe part of some data? Hope this helps, Katrin On 17.09.23 19:41, JITHIN N wrote:

Am using Koha 22.11.07. My server running 6 instances. I noticed my disk was filling up because worker-output.log was getting several hundred of these per second:

*[2023/09/17 22:41:14] [WARN] Frame not processed - malformed JSON string, neither tag, array, object, number, string or atom, at character offset 0 (before "You must log in usin...") at /usr/share/koha/bin/workers/background_jobs_worker.pl <http://background_jobs_worker.pl> line 118. main::catch {...} /usr/share/koha/bin/workers/background_jobs_worker.pl <http://background_jobs_worker.pl> (120)*

while checking the terminal it ran a number of background jobs and CPU usage became very high. can I have any solution for this?
