Hello,
>From time to time we receive following event from application (Adobe Campaign - former Neolane): PostgreSQL error: lost synchronization with server: got message type "Z", length 0\n (iRc=-2006) Last time underlying sql statement was an update. At the backend side there is: LOG: unexpected EOF on client connection with an open transaction From http://doxygen.postgresql.org/fe-protocol3_8c_source.html#l00450 I can read: 444 /* 445 * handleSyncLoss: clean up after loss of message-boundary sync 446 * 447 * There isn't really a lot we can do here except abandon the connection. 448 */ Could something else than network cause this event?
