PostgreSQL Database freezes during backup then generates drwtsn.exe process

I'm running PostgreSQL 8.3 on a Windows 2003 machine (pgAgent service is
also installed and running).  The system is running as a redundant
database server.  Thus, backing up from one machine to another, and
transferring over WAL logs.  In the postageSQL log files there are
several error messages that read:

'could not rename file, no such file or directory'  


Eventually, postgreSQL 'freezes', I'm unable to access the database, and
there is no logging.  I find a drwtsn.exe process running under the
postgres account in Task Manager.  If I kill the drwtsn PostgreSQL
service will stop.  I can then restart it and the database will run as
expected for a few days.  


Has anyone encountered this problem before?  If so, were you able to
find a solution?


Thanks for any help in advance.
