warm standby issues

Hi List;

I'm setting up a warm standby server on version 8.1.9

I setup a recovery.sh script to keep the standby cluster in recovery
mode waiting for the next WAL segment. everything works fine as long
as the standby server is in recovery mode. I see the recovery taking
place in the postgres log of the standby server. I've set it up to
exit the recovery.sh script if it see's a trigger file (to bring the
standby online).

when I create the trigger file I see this:

copy /home/postgres/healthCareCoding/WAL/000000010000000000000004
pg_xlog/RECOVERYXLOG
`/home/postgres/healthCareCoding/WAL/000000010000000000000004' ->
`pg_xlog/RECOVERYXLOG'
LOG: restored log file "000000010000000000000004" from archive
LOG: could not open file "pg_xlog/000000010000000000000005" (log file
0, segment 5): No such file or directory
LOG: redo done at 0/4FFFE90
PANIC: could not open file "pg_xlog/000000010000000000000004" (log
file 0, segment 4): No such file or directory
LOG: startup process (PID 9348) was terminated by signal 6
LOG: aborting startup due to startup process failure
LOG: logger shutting down

I see that the log 000000010000000000000004 was restored, but then
when it tags the redo as done it complains that it cannot find the
same log.

If I re-start the standby cluster and select count(*) from my test
table (the table I'm inserting data into to fill the logs) I get this:

postgres=# select count(*) from t1 ;
ERROR: xlog flush request 0/113730C is not satisfied --- flushed only
to 0/1135018
CONTEXT: writing block 1500 of relation 1663/10819/16384
postgres=#

My recovery.sh code is below, thanks in advance for any help...
