BUG #2099: too many private dirs ?

The following bug has been logged online:

Bug reference: 2099
Logged by: Tom
Email address: tom.zschockelt@flender.com
PostgreSQL version: 8.1.0
Operating system: win2003 server
Description: too many private dirs ?
Details:

we got the following error in our environment:

2005-12-08 13:43:04 ERROR: too many private dirs demanded
2005-12-08 13:43:04 ERROR: checkpoint request failed
2005-12-08 13:43:04 HINT: Consult the server log for details.

Our environment is the following :
1 x win2003 server with postgresql 8.1.0-2
DB-Data on a NAS-device (mounted as network drive)

The error occurs when we want to create a new database in the
postgres-cluster. Creation of databases are only possible a few hours after
restarting the postgres
service.

Any idea ?

I can see a possible mechanism for this, but it requires assuming that
there have been repeated prior failures in the bgwriter/checkpointer.
What else is in the postmaster log?

Hi,
