How to resolve packet loss & tranmission errors on a linux server. Please suggest.

[unix syzadmin]

Hi,

In one of our Linux servers (RHEL-AS2.1 Update 5), the ping response was
very slow.  From the following, it looks like there is a packet loss&
transmission errors (80% packet loss, TX-ERR=39962)  .  Please suggest how
to resolve this issue.

[root at bangpcrh212 root]# ping bangapps
