Hi, Here is what happened: I have Zope 2.4.1, Python 2.1, Xron-0-0-10 installed. I have three Xron Methods that run every 15 minutes and one that runs every day at 2 am (call it reportsender). At 2 am reportsender started and finished ok. Just after reportsender finished it's work, another Xronmethod was called - it finished with ok status. Than: 2002-02-09T02:00:03 ERROR(200) Catalog uncatalogObject unsuccessfully attempted to uncatalog an object with a uid of /TO/Reports/reportsender And reportsender started being called a few times every second. ....Until Data.fs has reached 2 Gb limit.... (it was at 02:51 am). From that time to about 11:36 am Zope was reporting errors reading Data.fs. At 11:36 it stopped reporting errors and started to work fine - nothing else suspicious happend. The only problem was that old data.fs disappeared and new one, empty appeared. I have here two problems: 1. How Xron could call reportsender million or more times? 2. How could my Data.fs had disappeared? The day before (08.02.2002) reportsender was moved (cut+paste) from one place to another. First it wasn't under any SiteRoot, after copying it came under SiteRoot and a UserFolder (i think it is the source of problem). 2002-02-09 01:00 - 13 GB free disk space Thank you for any suggestions why that happened
