TMM crashes when reloading a large NVGRE config multiple times.
The crash happens only after multiple reloads. After TMM restarts, the system is stable.
Reloading a large NVGRE config (greater than 1000 NVGRE tunnels) multiple times in a row causes a TMM crash.
There is no workaround to this issue.
Fixed a number of NVGRE config cleanup issues that were causing the crash.
