I am getting the following errors during a loadtest with around 120 users, 
10gR2 on Linux X86 RedHat EE V3.

 

TNS-12518: TNS:listener could not hand off client connection

 TNS-12547: TNS:lost contact

  TNS-12560: TNS:protocol adapter error

   TNS-00517: Lost contact

    Linux Error: 32: Broken pipe

 

I tried Oracle's suggestion on enabling and disabling 
DIRECT_HANDOFF_TTC_LISTENER=on/off, but of no vail.

 

Has anyone seen this error? Please chare your experiences, resolution.
