Since 14:45 yesterday 13 demos are failing for the 32-bits linux buildbot. While writing this email, suddenly they worked again.

The 64-bit linux and the mac were still running the demos, until three demos started failing for the mac as well during the night. The 64-bit linux machine is still running the demos, but it has 32 GB of memory. The error from the mac looks like this, indicating it might be a memory problem:
Initializing DOLFIN version 0.7.2.
Initializing PETSc with given command-line arguments.
Saved function u (discrete function) to file cahn_hilliard.pvd in VTK format.
Starting Newton solve.
   Assembling matrix over cells (finished).
   Assembling vector over cells (finished).
