Problems with Streaming Replication and PostgreSQL 9.2.2

Hello, everybody

I have one problem and I need some help.

My environment: one master and one slave (PostgreSQL 9.2.2).

My cluster has about 160GB and pg_basebackup to syncronize them (master and slave).

The syntax is:

pg_basebackup -h productionaddress -p productionport -U productionuser -D datadirectory -P -v

My recovery.conf:

standby_mode = 'on'
 
primary_conninfo = 'host=productionaddress port=productionport user=productionuser'

archive_cleanup_command = 'pg_archivecleanup /slave/transactionlogs %r'

My postgresql.conf: (master)

wal_level = hot_standby

checkpoint_segments = 10

archive_mode = on

archive_command = 'rsync -Crap %p postgres@slaveaddress:/slave/transactionlogs/%f'

max_wal_senders = 1

wal_keep_segments = 50

My postgresql.conf: (slave)

checkpoint_segments = 10

hot_standby = on

In my slave (logs) I have the following erros: My first attempt

In my slave (logs) I have the following erros: My second attempt

I had the same problem, but in different files (pg_clog):

First attempt:

2013-03-07 15:58:25 BRT [11817]: [5-1] user=,db= FATAL:  could not access status of transaction 30622931
2013-03-07 15:58:25 BRT [11817]: [6-1] user=,db= DETAIL:  Could not read from file "pg_clog/001D" at offset 49152: Success.

Second attempt:

2013-03-11 12:07:53 BRT [5862]: [5-1] user=,db= FATAL:  could not access status of transaction 36529670
2013-03-11 12:07:53 BRT [5862]: [6-1] user=,db= DETAIL:  Could not read from file "pg_clog/0022" at offset 212992: Success.

When I started the synchronism at the first time (no data), it was OK. Now, my cluster has about 160GB and when the replication finishes I have these problems. I noticed that pg_clog/current_file is the problem.

Any idea? Suggestions?

Thank you.
