SSL connection lost after long-lasting copy command

Hi,

While copying a large'ish file (~ 7.6 million rows) into a table with:

\copy [tablename] ([columns]) FROM '/path/to/large/file' NULL AS ''

The command stopped running after a few minutes with the message:

---<--------------------cut here---------------start------------------->---
server closed the connection unexpectedly
    This probably means the server terminated abnormally
    before or while processing the request.
---<--------------------cut here---------------end--------------------->---

Checking /var/log/postgresql/postgresql-8.4-main.log, there's a long
series of checkpoint_segments (only the last 2 shown) and an SSL error:

---<--------------------cut here---------------start------------------->---
2010-02-09 10:47:03 CST LOG:  checkpoints are occurring too frequently (6 seconds apart)

Any pointers appreciated.  Thanks.
