DB deadlocks involving DemoXFromsPostsGeneratorJob, loadbalanced
Hi
I am not fully aware of the background of that job. When I look in the source code I can see that it used from the XFormsViewer gadget, probably it is used from the gadget to generate som kind of data.
Anyway it should be perfectly fine to disable it.

Hello fellow EPiServians
I've upgraded a 4.62 solution to 6.0 some time ago, and it seems to run OK. Now, our database admin have bought a new survailance tool for the database server and have descovered deadlocks at random intervals between 3 and 20 minutes. He send me a trace and if i'm rading the trace info right, this is the two calls that give the deadlock:
10 Mar 2011 13:38:29exec netSchedulerExecute @pkID='79833BD4-56D0-46C6-95BD-B436A70C4A80',@nextExec='Mar 10 2011 12:38:26:203PM',@utcnow='Mar 10 2011 12:38:29:660PM'
10 Mar 2011 13:38:29exec netSchedulerExecute @pkID='79833BD4-56D0-46C6-95BD-B436A70C4A80',@nextExec='Mar 10 2011 12:38:26:203PM',@utcnow='Mar 10 2011 12:38:31:327PM'
I've looked up the job name to be DemoXFromsPostsGeneratorJob. It executes every 5 seconds.
DB admins don't like deadlocks as they cost performance, but once in a while are ok. In our case, we have the website hosted on two webservers with one database. This means we have two schedulers running at therefor we have this performance issue.
Well, on to my question: What is the perpose of DemoXFromsPostsGeneratorJob? We don't use XForms, so is it OK to disable it? Is it a leftover from episerver 4?
