Hi,

When running this code:

K.<a> = NumberField(x^2 + 1)
K.is_galois()

These two lines shouldn't be invoking maxima at all, and work for me. Are you sure it's not something else. Was x something other than the variable x?

I get (in part) this error:

execfile("/home/zsharon/.sage/sage_notebook/worksheets/admin/3/ code/2.py")
b18
Maxima crashed -- automatically restarting.

The full error log is here: http://pastebin.com/eDWv56mq

I've tried reinstalling sage, completely-uninstalling-then-installing
sage, and reinstalling maxima.  No change.

Re-installing Sage is unlikely to change anything,

        •
(%i2) xmalloc: out of virtual memory
        •

Seems to indicate that you're problem is that you're running out of memory.

Any ideas?  I'd prefer to not have to reinstall the whole OS.

Is there a surefire way to completely remove sage?  As I said above, a
"complete" uninstall and then reinstall did not fix it.

Just remove the sage directory, that's all there is to it. Files are also put in ~/.sage (which stores all your notebooks), though as mentioned above, that probably won't help.
