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?

PostgreSQL version:

postgres=# select version();
                                                    version
----------------------------------------------------------------------------------------------------------------
 PostgreSQL 9.2.13 on x86_64-unknown-linux-gnu, compiled by gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-11), 64-bit
(1 row)


Thank you
Marek
