[xwiki-users] timeout in job scheduler?

[Pascal BASTIEN]

Hello,

I created a job scheduled in scheduler, but sometime my job seem to be failed 
sometime.

In my groovy job I add some logging system: some text sent to a xwiki page+save 
but didn't find interesting things.
Of course I have some loops (I things) in my script (to list groups member):
        Members = 
xwiki.rightsmanager.getAllMembersNamesForGroup("${GroupName}") //extrait les 
users du groupe
        Members.each {
                MyMember = xwiki.getDocument(it)

I wonder, Is there a timeout associated to the script that runs and is there 
feedback in the event of an error (or a way to activate logs for job scheduled)?

Thxs
