The updated FlexNet (FLEXlm) version (based on Flexera Software’s FlexNet Publisher Licensing Toolkit 11.11.0) was released in August 2012 and is available as a public download as well as the updated License Administration Guide.
Here are the news in Version 11.11.0
• Support for XenServer in virtualized environments
• New hostid keyword VM_UUID to support binding to a virtual machine on VMware, Microsoft Hyper-V, and XenServer platforms
No words about if there are any bug fixes but if you experienced unknown problems with the license manager it can be worth trying if updating will help.
lmgrd.exe, lmutil.exe and lmtools.exe are all 11.11 now.
