Changeset: 4f72f353b22b for MonetDB
URL: http://dev.monetdb.org/hg/MonetDB?cmd=changeset;node=4f72f353b22b
Modified Files:
gdk/gdk_utils.c
Branch: default
Log Message:
Patch to previous changeset.
An RSS shrinkage of 1024th of total RSS isn't good enough. When there
is a lot of memory available, this can well be more than the amount by
which RSS shrinks, so that our cleanup never triggers. Instead,
trigger on a shrinkage of a limited number of pages.
