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

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.
