APAR status
Closed as program error.
Error description
In a multi-cell environment where there are identical web-modules in more than one cell, affinity will not be preserved unless the first module we check happens to be the one we have affinity with.  Since we load balance across the cells, choosing sequentially among them, this gives you only a 1 in N chance to keep affinity, where N is the number of cells with that web-module available.
