Problem with multiple concurrent ERXAbstractTask each with his own objectstore

hello,

i am now trying for a while to get multiple background tasks running  =

concurrent
each with his own object store coordinator.
each of the task iterate over a lot of enterprise objects.
the used editingcontext is disposed in the loop every 1000 records and
a new one is created.

all works fine but once in a while a get and error from the  =

eodatabasecontext
that an eo can't be fetched with global id but that id exists!

er.extensions.eof.ERXDatabaseContextDelegate =

$ObjectNotAvailableException: No XXX found with globalID: <XXX: [ID:  =

'64294'] >
         at  =

er.extensions.eof.ERXDatabaseContextDelegate.databaseContextFailedToFetc =

if i run the task sequential i got no errors.

i think it is a problem with the concurrency.
does anybody have some hints what is to be considered when running  =

task concurrent?



thanks,
