<div><br></div><div>With help of <i>top</i> I see that as soon as i hit "Show Completed Jobs" button, CUPS starts to use 100% of CPU, then gets killed and respawned with a new PID. <i>error_log</i> shows that CUPS receives job listing request, finds out it needs to process 749 completed jobs from 53 printers, reads their attributes one by one, and then suddenly dies as if something has killed it.</div>
<div><br></div><div>Is there an internal timeout (60 sec?) that would kill cupsd in this situation? </div><div>Is there a way to make CUPS process these jobs page by page in order to reply faster, instead of going through all those completed jobs? </div>
