Scenes:
- when I do not use create IncrementalIdStrategy instance I call RuntimeSchema.getSchema(Class<?> type) to get runtime schema it works well.
- when I create the IncrementalIdStrategy instance and deploy my web app into my cluster some http-exec-bio threads get stuck on RuntimeSchema.getSchema(Class<?> type) line 140
here is how I create the IncrementalIdStrategy instance,
new IncrementalIdStrategy.Factory().create()

Hope your feedback and sorry for my poor english.

If you use multiple instances/jvm, there is no guanantee that the id generated for a certain class is the same across your instances.
I suggest you use ExplicitIdStrategy if you know the classes that need to be serialized ahead of time.  Otherwise, use the default.
some http-exec-bio threads get stuck on RuntimeSchema.getSchema(Class<?> type) line 140
return getSchema(typeClass, ID_STRATEGY);

That doesn't help.  Post your complete stacktrace (a sample that replicates the issue would be better)
here is how I create the IncrementalIdStrategy instance,
new IncrementalIdStrategy.Factory().create()

thank for your time.
My web application is deployed into a cluster.Some hosts can not response http request so I take lots of thread stacks to see what happens.
Please NOTE that not all hosts behaves badly, just some of them. 
Almost all threads get stuck and stacks seems like the following:

"http-bio-7001-exec-250" #660 daemon prio=5 os_prio=0 tid=0x00007f6005f73800 nid=0x410f in Object.wait() [0x0000000061870000]
   java.lang.Thread.State: RUNNABLE
        at io.protostuff.runtime.RuntimeSchema.getSchema(RuntimeSchema.java:140)
        at com.*.*.util.Serializations$PBSerializerType.toBytes(Serializations.java:112)
