Websphere - java.io.IOException: Async IO operation failed

1. The problem only happens when finishBufferResponse request is processed asynhronously and it is possible to prevent the problem by forcing all such requests to be handled synchronously. This can be done by setting the webcontainer custom property:

com.ibm.ws.webcontainer.channelwritetype=sync


2. The above errors can cause the Http connections to be terminated and can cause session timeouts. To prevent this, you may need to set this custom property
