Nuno,
I noticed a similar unexplained restriction
on our Linux 2.4. We have 512 MB physical memory,
no swap partition, and for some reason I cannot
malloc more than 256 MB. The Unix errno just says
'Cannot allocate memory'.
On our other machine with 900 MB RAM and 512 MB swap
I can malloc 900 MB.
What is your my.cnf like? Is it possible that you
have allocated so much memory to PostgreSQL, MyISAM,
and other programs that the 2 GB or 3 GB you have is
almost totally used?
Regards,
Heikki
