Cause
Um problema de código foi introduzido no DLm versão 5.4.0.0, o que pode causar um atraso na liberação do buffer do dispositivo após o uso durante operações de eliminação ou exclusão.
Esse é um problema de falta de buffer em que o pool de buffer fica esgotado durante operações intensas de eliminação ou exclusão, causando atrasos em cascata quando outros threads que tentam obter um buffer precisam esperar.

Resolution
O cliente deverá executar a correção imediata, reiniciando o aplicativo Virtuent ou reinicializando o VTE.
Esse problema é resolvido no DLm 5.4.0.1 e no código posterior.
