Hello,
we have a database master Version:
PostgreSQL 9.1.6 on x86_64-unknown-linux-gnu, compiled by gcc (Debian 4.7.2-2) 4.7.2, 64-bit
and a WAL-Replication Slave with hot-standby version:
PostgreSQL 9.1.9 on x86_64-unknown-linux-gnu, compiled by gcc (Debian 4.7.2-5) 4.7.2, 64-bit.

Since a few days we had problems with the Linux OOM-Killer.
Some simple query that normally take around 6-7 minutes now takes 5 hours.
We did not change any configuration values the last days.

Are we affected by this bug:
https://wiki.postgresql.org/wiki/Nov2013ReplicationIssue ?

Regards,
Basti
