checkpointing shared memory fails

    Details

      Description

      I created a VE to host a postgresql server. During migration of this server the some postgresql processes crashed with following error:

      PANIC: hash table "Shared Buffer Lookup Table" corrupted

      First I asked on the pgsql-general mailing list and they wrote, it is a problem during dumping the memory.

      I tested it on Debian 5.0 with the given openvz kernel.

      Steps to reproduce:

      * install a VE with postgresql
      * enter the VE and connect to the postgresql server
      * checkpoint the VE
      * restore the VE
      * try to query the database
