Oracle 11gR2 - linux issue

Hi guys,

I'm configuring my Oracle 11gR2 RAC @ SUSE 10 Enterprise Server, all was good, until yesterday, when I installed asmlib and then created 2 diskgroups too, still all well.

Don't know what went wrong on node1 that I'm continuously getting this error:
Last login: Fri Aug 13 16:58:51 2010
oracle@oracle-node1:~> ls
ERROR: ld.so: object '/home/oracle/libcwait.so' from LD_PRELOAD cannot be preloa ded: ignored.
authorized_keys Desktop Documents oradiag_oracle PROFILE tmp

node2 is good and no issues at all, can see all my ASM disks from both the servers, but when trying to install Grid, it is failing at ssh connectivity, because whenever I run a command it gives this error ...
oracle@oracle-node1:~>
oracle@oracle-node1:~> ssh node2 date
ERROR: ld.so: object '/home/oracle/libcwait.so' from LD_PRELOAD cannot be preloaded: ignored.
ssh: node2: Name or service not known
oracle@oracle-node1:~>

Have tried a lot ... but still no clue, and interesting part is this that there is no libcwait.so on node2 ... at /etc or /lib or /usr/lib too ... don't know, why it is looking for this file now.

Please any suggestion, advice or help will be highly appreciated and admired.
Thanks in advance.

thanks madunix ... but it was an environment variable problem, the .bashrc was having some problem, as I removed it, it worked fine, thanks for you help, but it was just a bad environment variable, which was causing this problem.

but there is no alert log yet ... as nothing has been done, I'm stuck at Grid installation, step before db installation, and it is also stopping where it is trying to ssh ... from node 1 to node 2 and vice verse ...

but keep in mind that it was working fine and suddenly only one node (node1) is having this issue, where as node2 is good, no problem at all.

Do advice how to fix, this annoying problem ... thanks.

64 bit

and here is the output

oracle@oracle-node1:~> env | grep LD_LIBRARY_PATH
ERROR: ld.so: object '/home/oracle/libcwait.so' from LD_PRELOAD cannot be preloaded: ignored.

to solve it, get the library libcwait.so (or a patch, can't remember the no. XXX) from metalink...
You can download patch from OracleMetaLink (http://metalink.oracle.com). This patch creates the /usr/lib/libcwait.so library and creates entry in /etc/ld.so.preload file so  the /usr/lib/libcwait.so library is always preloaded.
