Bug? Bubbles in wind object

I tried to run a 2D simulation where a Wind passes by a Wire surrounded by a cylindrical magnetic field embedded inside an Ambient medium. Wire object extends Clump object to a cylindrical shape.

For this run,

the grid consists of a square of 2.5 mm; magnetic field at the wire surface is 7.5 T; Wind and Ambient temperature is 300 K; Wire temperature is 3e-3 K; Wind density is 1e-5 g/cc; Wire density is 7.5e-2 g/cc; Ambient density is 7.5e-7 g/cc; Wind velocity is 150 km/s.

sigma = 10 at surface of wire

Description of bug: bubbles inside the wind appear and grow to dominate the simulation.

MPEG attached.

Maximum time of movie does not exceed 0.6 ns. Left side: log density Right side: log energy
