Re: [MarkLogic Dev General] Strange issue with xdmp:node-delete
I concur that the fact ML seems to stop responding does sound like a deadlock. Looking at cluster status, and inspecting the execution queues might reveal a request that doesn’t seem to return. Your code is not using eval or invoke, though, so i don’t think you can create a deadlock with just that code. Could it be though that you are invoking below code from elsewhere where you might be reading or updating same kind of content?

Re: [MarkLogic Dev General] Strange issue with xdmp:node-delete
Just in case, you can confirm that the node you are about to delete is
indeed from a stored document with something like the following :
xdmp:log(fn:document-uri(fn:root($node)))

Re: [MarkLogic Dev General] Strange issue with xdmp:node-delete
Hi Mister Florent,
Thks for your answer.
There is no symptom at all: no exception, no specific log, no deletion.
When I run the 'real' script on QConsole (or Oxygen connected through xdbc
to ML), it returns the focus after a while (whitout SVC-EXTIME) without any
deletion.
I'm trying with a colleague to simplify the script and recreate a readable
case for everyone.
For now it seems that the sem:sparql combined with sem:store has some
influences on this behavior
So I will come back soon with a simplified script.
