This is a Network File System (NFS) problem with virtual IP and locking.
When installing ArcGIS software on a Red Hat Enterprise Linux (RHEL) 5 machine as a network client user, the installation shops responding while registering libmwxml.so.
This bug could potentially happen with any version of software when logged in as an RHEL 5 NFS user.
The problem occurs when RHEL 5 Client A attempts to acquire a POSIX lock by way of NFS to an IP address, but receives a reply from a different IP address.
First RHEL 5 NFS client attempts to get exclusive POSIX locks on a file. Then, RHEL NFS server (which is multihomed and has multiple IP addresses) responds with the wrong IP address, for example:
eth0 IP: 10.49.6.6
eth0:0 IP: 10.49.6.7
The problem manifests when Client A attempts to acquire a POSIX lock by way of NFS to 10.49.6.6 but receives a reply by way of IP 10.49.6.7.
Note: This issue was addressed in Red Hat release RHEL 5.5.
Create and install ArcGIS software products as a local user.
RHEL 5 customers are advised to contact Red Hat Support and refer to: Red Hat Bugzilla: Bug 500653 - NFS: problems with virtual IP and locking.
