APAR status

  • Closed as program error.

Error description

  • When using WPAR setup under AIX, with each WPAR
    configured
    as an NFS client, it is possible that asynchronous
    READDIR
    operations fail with ESTALE error under the WPAR.
    Asynchronous READ and WRITE operations work fine, and
    all operations work fine in the global environment.
    
    Applications such as SAP and other OEM programs could
    abort when
    reading NFS directories from a WPAR.
    
    
    An example error:
    
    $ xe   /sapmnt/software/SCM/702_upgrade/download_dir/
    
    uabend:err code=1,p1=00000000,p2=00000000,p3=00000000
         IOT/Abort trap
    (coredump)
    

Local fix

Problem summary

  • When using WPAR setup under AIX, with each WPAR configured

    operations fail with ESTALE error under the WPAR.
    

Problem conclusion

  • Use the correct CID for READDIR operations from WPAR
