Hi, this was an extract from the old logs, before Soumya's suggestion of changing the rquota port in the conf file. The new logs are attached (ganesha-20150611.log.gz) as well as the gstack of the ganesha process while I was executing the hanging showmount (ganesha-20150611.gstack.gz). Thanks,
Alessandro
