Today in our production environment - Author we noticed that few items in the "Replication Queue" were pending for a long time and we had to manually clear those items. Does anyone know what could have caused it? We checked and connection to Publisher was OK.
Thanks in adavance!
There could be many reasons why replication may not work. Did you check the Replication log and error.log to see if there were any errors/messages which indicated any information about the pages that were stuck in the queue? Did you retry to publish the stuck pages and did they get published this time?
