Abstract
For the GI/G/1 queueing model with traffic load a<1, service time 
distribution B(t) and interarrival time distribution A(t), whenever for 
t→∞1−B(t)∼c(t/β)ν+O(e−δt),c>0,1<ν<2,δ>0,
and
∫0∞tμdA(t)<∞ for μ>ν,
(1−a)1ν−1w converges in distribution for a↑1. Here w is distributed as the 
stationary waiting time distribution. The L.-S. transform of the limiting 
distribution is derived and an asymptotic series for its tail probabilities is 
obtained. The theorem actually proved in the text concerns a slightly 
more general asymptotic behavior of 1−B(t), t→∞, than mentioned 
above.
