We report on the hysteresis and avalanche behavior of{sup 4}He capillary condensing into the nearly cylindrical pores of the porous membrane Nuclepore. Following capillary condensation, withdrawal of the {sup 4}He results in distinct jumps or avalanches where 10{sup 7} pores can be involved in a single avalanche. By using Nuclepore with 2000{angstrom} and 300{angstrom} pore diameters, we find that the avalanche distribution depends on details of the pore structure.
