occasionally (not too often), we are running a background import task, which uses its own EO stack: at launch, it creates a new EOObjectStoreCoordinator (and for it it creates an ERXEC and uses it to import data). When done and saved, the coordinator is disposed and released. The rationale is that the imported data might be big and we don't want to limit normal workers processing to wait until the import saves its results into the database.

For a long long time it worked reliably and without a glitch.

Lately, it often (though by far not each time!) happens that

(i) a save in the background task reports the following exception:

(ii) after that, usually no more exceptions are reported, but the ERXObjectStoreCoordinatorSynchronizer does not seem to work properly anymore, and it often happens that the changes done in the background task are not visible in the main OSC for awhile.

From the user's perspective it usually means that the import is finished, but the imported data is not visible for a long long time (does not seem to be just a fetchTimestampLag, for newly logged-in users with their new sessions and new ECs still don't see the imported data for awhile. Frankly, I can't see what the H. might be the culprit :/ )

(iii) another problem which seems to be also caused (perhaps indirectly) by the above exception is that the application cannot be normally quit from JavaMonitor, reporting upon an attempt

Any idea what might be the culprit and how to fix it?

Thanks and all the best,
