Oracle 11.2.0.1 database fails to start :  ORA-12547 TNS lost contact + sigchld child exited @ 0 + kernel trap invalid opcode symptoms

Hello,

I'm unable to restart Oracle 11.2.0.1 database (RHEL 5.9 environment) after reboot.  TNS listener starts, but database fails to start.  lsnrctl status shows "The listener supports no services".  Process grep shows tnslsnr running only -- no database processes are running.  Local attempt to connect to the database as sysdba returns: ORA-12547 :TNS : lost contact.

System log (/var/log/messages) has kernel message:  kernel: oracle[12601] trap invalid opcode rip:2307748 rsp:7fff952560a8 error:0.  

Excerpt strace sqlplus / as sysdba:

...

...

getrlimit(RLIMIT_NOFILE, {rlim_cur=1024, rlim_max=64*1024}) = 0

Howdy, Stranger!
