The system is has solutions.
You can use Singular, which is part of Sage:

Hi!
How do I construct matrix orderings in Sage?
I had a look at PolynomialRing and TermOrder and did not find
anything.

Hi!
I can't sleep, when fearing PolyBoRi could calculate wrong:
Actually, it's probably just about the wrapper.
My CVS, which is very much the same as 0.6.3 gives me:
l="a111,a112,a121,a122,b111,b112,b211,b212,c111,c112".split(",")
In [2]:declare_ring(l, globals())
Out[2]:
In [3]:ideal=[a111 *
Hi!
If I didn't made an error converting this input, PolyBoRi returns an
answer immediately.
Indeed [1].
And of course it is the GB for all orderings.
Regarding "seeing, what is going" use "prot=True".

Hi!
The program is located on a local disc, it is just my home on a NFS
file system.
I tried linking .sage to /tmp/blupper (I hope, that is not a
trademark)
and everything worked.
Then I removed the link and tried again with my normal nfs home and
produced the following strace.
Best regards,
Mic
Hello!
The same problem appears here.
I suppose, it could be a problem with the NFS home directories.

Hi!
I have the same problem here on our compute server.
Could it be a problem with file locking in NFS-home-directories?
