Symptoms

The customer noticed several issues:
- The custom portal login system failed to process incoming logins
- There are STUCK threads on SOA and OSB servers leading to WLS overload and automatic shutdown
- The total amount of sockets on WLS increased drastically.
- The logs shows error while processing requests from SOA to OSB and from OSB to SOA. Some requests timed out, some requests were staying forever.
Overall that lead to system being unusable.
