At a client of mine we’re steadily rolling out 3k instances of XenDesktop. One issue that surfaced early on is that Weblogic Workspace v10.2 crashed on launch after the deployment of the Citrix XenDesktop Virtual Desktop Agent (VDA). The client had packaged/certified the 3.03.059 release of the VDA. After deploying the VDA and rebooting, user’s of Weblogic Workspace 10.2 were unable to launch the application. The crash that would appear is this:
It turns out that this particular issue is caused by applications that attempt to acquire a large allocation of memory during startup. Something about the XenDesktop VDA breaks this ability. The good news is that Citrix has found this issue and corrected it in the new XenDesktop 3.0 Feature Pack 1 VDA (3.1.3236) which can be downloaded at CTX121590
The specific fix in this VDA that resolves the Weblogic issue is:
If an application requests a large block of contiguous memory, the allocation might fail.
Yet another situation that upgrading to the latest and greatest and sometimes be a good thing. The good news is that this VDA can be installed right on top of the existing VDA without incident.
