ORA-12547: TNS:lost contact at execution of svrmgrl/sqlplus

Hi all,

We are running Oracle 8.1.5 on HP-UX 11.0. Recently we started getting an error 'ORA-12547: TNS:lost contact' whenever trying to connect to svrmgrl.
No upgrades on the server, it was working fine before. I searched the metalink and tried everything (relinking). The listener starts/stops ok.

Here is the output of svrmgrl execution:

gamprime:[/pkg/app/oracle/product/8.1.5/bin]$ svrmgrl

Oracle Server Manager Release 3.1.5.0.0 - Production

gamprime:[/pkg/app/oracle/product/8.1.5/bin]$

TIA
Suhasini.
