Symptoms

This problem occurs on a High Availability environment.
This is a 2-node clustered production WebCenter (PS2) Spaces(WLS_Spaces) deployment and a (custom) portlet provider developed with portlet bridge and deployed in WLS_Portlet (clustered as well), with 2-node apache 2.2 cluster (hardware balanced) with virtual host and WLS Proxy Plugin enabled in front of them.

Custom portlets have been created in JDeveloper 11.1.1.3 and exposed as WSRP with the portlet bridge.
Intermittently, one of these portlets fails to display, showing this message 'Portlet Unavailable'.

Once the message occurs, the only way  to resolve the issue is to restart the managed server where the portlet provider is deployed.

This is the error stack seen when the portlet error occurs:
