 The callstack "_ZN11OracleHooks8readHookEiPvm" suggested that the problem is caused by third-party security software, eg IMPERVA

/opt/imperva/ragent/bin/ragentwd --daemon -r /opt/imperva/ragent -d /opt/imperva/ragent/etc -v /opt/imperva/ragent/var
 

SOLUTION
Stop third-party security software (eg imperva); (sometimes even uninstall it from the system)
