Reported using DrKonqi 1749874 1 stefan.bruens 2018-05-03 22:37:34 +0000 Git commit f57c4bc27b81f2b40d910d376a0bb531cd8472c6 by Stefan Brüns. Committed on 03/05/2018 at 22:37. Pushed by bruns into branch 'master'. Avoid infinite loops when fetching the URL from DocumentUrlDB Summary: Some users apparently have DBs which contain infinite loops in the idTree (a parentId pointing to itself or one of its children). This manifests in either crashes due to exhausted memory and/or the process being stuck with 100% CPU load. The problem can only be completely solved by either recreating the DB, or by cleaning the DB from any problematic records. As in interim solution, stop the code from crashing.
