1.2 Bug Fix release[edit]

  • PID - issue resolution

postgres connections[edit]

  • since core service 1.2 deployment and the postgres connections, we have had experienced quite unusual memory consumption of postgres. From ca. 10 connections to the database, one of these connections consumes enourmous RAM and is never set free (4-6 GB). The same behavior is on all servers, even those which are simply set as default and have no midnight fetching of data.
  • Note that this process is not the postmaster process itself, but is the escidoc-core connection process to escidoc-core database.Our servers start to consume after a while a lot of swap and then after some time the system stops functioning.The total memory of the server where this is really critical is 32 GB, where postgres database itself uses only 1/4 of it.
  • Can you please investigate a bit or let us know if you have some ideas how to monitor this problem?
