Cause:

Usually this error is occurring as per your env. setting. Try to check which .env file using this option.

Now to overcome this issue, immediately you can set LD_PRELOAD_32= to Null value and export this variable.


Solution:

bash-3.00$ env | grep LD_PRELOAD_32
LD_PRELOAD_32=/usr/lib/extendedFILE.so.1
bash-3.00$ LD_PRELOAD_32=
bash-3.00$ export LD_PRELOAD_32
bash-3.00$ env | grep LD_PRELOAD_32
LD_PRELOAD_32=
bash-3.00$ su - oratest
