APAR status
Closed as program error.

Error description
A key piece of storage is not being initialized in the
optimized  local communications layer of WebSphere on z/OS
(aka local comm).  If the storage happens to be a value of all
zeros,  then local comm is not functional and will hang any
requests over local comm to the server.

****************************************************************
Requests from local clients to a WebSphere server may hang and
timeout due to an initialization problem in which a key piece
of storage is not initialized correctly.  If this occurs, any
requests over the optimized local communications path, also
known as local comm, will fail.  When running the dumpNameSpace
utility, the following exception and minor code may be seen:
org.omg.CORBA.COMM_FAILURE:   vmcid: 0xc9c26000  minor code: A37
Problem conclusion
WebSphere initialization has been changed to properly
initialize the storage in question.

APAR PK45278 is currently targeted for inclusion in Service
Level (Fix Pack) 6.1.0.11 of WebSphere Application Server V6.1
for z/OS.
