Abstract Grid middleware usually makes use of several software modules that due to
their complexity and development approach may have some latent bugs and
leaks. These bugs can cause visible performance failures and undesired ser-
vice crashes. To cope with this sort of transient failures we present a proactive
software rejuvenation approach that exploits the use of virtualization middle-
ware. To prove the effectiveness of our mechanism we decided to apply it to
OGSA-DAI, a sound example of a middleware that has been widely used in sev-
eral Grid-related projects. OGSA-DAI makes use of Tomcat/Axis as the SOAP
