Getting Bus Error(CoreDump) from 11i Apps (11.5.10.2) when connecting to 11gR2(11.2.0.3.1)

On 11i(11.5.10.2) apps tier, when trying to connect to 11gR2(11.2.0.3) database through command prompt 'sqlplus'; it's giving 'Bus Error(Core Dump)' and creates a core file.

Trying to ping using 'tnsping $TWO_TASK' works perfectly. Besides, telnet to the database host along with port gets connected.

But when trying 'sqlplus apps/<apps passwd>' from 11.5.10.2 apps tier; it throws away with coredump error.

Apps Release : 11i (11.5.10.2) on HP-UX B.11.23 U 9000/800
DB Release    : Recently migrated from 10.2.0.4 to 11.2.0.3.1(Jan'2011 latest psu applied) on Linux 2.6.32-100.26.2.el5

But when tried from desktop which has 10.2.0.1 client, it's connects to 11.2.0.3 database successfully.

Did relink on 11gR2   &   11i apps as well. But no luck.

Howdy, Stranger!
