What zaxxon said is absolutely correct. Here is another very very quick check if everything is ok with your memory (and, no, it is neither an in-depth analysis nor does it replace one): Issue the command "svmon -G" and observe the first line of output. Here is a sample:
I have marked bold the two relevant values. As long as "inuse" is higher or roughly equal to "virtual" everything is ok with the memory size. If "virtual" is (much) higher than "inuse" then your machine needs a memory upgrade - and the size of the upgrade will be at about the difference betweeen these two values, times 4k, as the numbers represent 4k-sized memory-pages.

QwtDoubleRect QwtCPointerData::boundingRect () const [virtual] Returns the bounding rectangle of the data. If there is no bounding rect, like
for empty data the rectangle is invalid: QwtDoubleRect::isValid() == false
Reimplemented from QwtData.
QwtData * QwtCPointerData::copy () const [virtual] Returns:
Pointer to a copy (virtual copy constructor)
Implements QwtData.
QwtCPointerData & QwtCPointerData::operator= (const QwtCPointerData &data)
Assignment.
size_t QwtCPointerData::size () const [virtual] Returns:
Size of the data set
Implements QwtData.
double QwtCPointerData::x (size_ti) const [virtual] Return the x value of data point i
Parameters:
i Index
Returns:
x X value of data point i
Implements QwtData.
const double * QwtCPointerData::xData () const Returns:
Array of the x-values
double QwtCPointerData::y (size_ti) const [virtual] Return the y value of data point i
Parameters:
i Index
Returns:
y Y value of data point i
