I have an SQL file with a set of about 3000 insert statements. This file is executed twice from a remote client machine running Windows XP. The first time it is executed against a Windows 2003 Server running PostgreSQL 8.0. The second time it is executed against a Windows 2003 Server running PostgreSQL 8.2. This setup has been in place for about a year now and never had any issues. However, I noticed today that all the file executions fail with [nativecode=could not send data to server: No buffer space available (0x00002747/10055)] error. I attempted to run the same file using pgAdmin III version 1.6.2, but every time the file is executed the only return in messages pane is the colon sign ":". No data is inserted. I attempted to run the same file using psql.exe and this worked without any problems. I also noticed that if I use less inserts, for example only a few hundred, the file executes fine. What could be the issue? Thank you. Nik
