StocksAndFisheriesKB

Legacy and GRSF stock records have been published smoothly.

However when we try to publish GRSF fishery records most of them (in the 99 %) of the cases the publishing fails with no error messages.
More specifically the response is the following:

An error occured while publishing records for grsf
gr.forth.ics.isl.grsfservicescore.exception.GrsfPublishingException: Fatal transport error
