Sync fails almost once a day (Openerp,openmrs,openelis, PACS)

Hi, We have been facing the sync issue each day. Deleting the markers table, event records and failed events restarting the services Works for few hours and fails again. Normally this happens when the patient flow goes up more than 350. Would like to discuss on this. Please suggest the pertinent solution. Do any body facing this issue. Expecting help and can be discussed thoroughly.

@sanjayap, are you using the new Sync 2.0 module?
