The time taken by classunloading is 27654ms.the total time taken is 31057ms.
If its repeating in the gc logs then we have to tune the JVM.

If the environment you are 

Use -Xgc:classUnloadingKickoffThreshold=<number> to specify the
number of classes to be available for unloading to kick off a
Global GC earlier, this will reduce the impact of the class
unloading time.

Also analyse the  application is having problem from the  dump using MAT tool.

Refer IBM Document
-Xnoclassgc should not be used to prevent class loading and unloading as it may lead to native OOM.

IBM link for noclassgc lead to OOM
