No, I mean it looks like you mounted the (a) swap file system on /tmp? If so, I'd be afraid this negatively influences all processes on the system.

What would happen if you did this:-
Code:
cd /target/directory
tar -xvf /path/to/tarball


I think that mounting /tmp using swap space is the default way that Solaris works, so I don't think there is an issue there unless you either boot (because, as swap, it doesn't persist) or you fill it and you server cannot swap.

Yes, "swap" stands for "memory". For illustration
Code:
$ mount -v | awk '$3=="/tmp"'
swap on /tmp type tmpfs read/write/setuid/devices/xattr/size=4096m/dev=5740002 on Tue Apr 11 14:48:23 2017

The -C seems to work, as said in the man page (see post#1), only with "c" and "r" but not with "x".
But you can work around
Code:
tar -xvf bent.tar -C /web/applications/configurations

with a sub-shell
Code:
cat bent.tar | (chdir /web/applications/configurations && tar -xvf -)

The file - is stdin.
Or the other way round, give the path to the archive file
Code:
(cd /web/applications/configurations && tar -xvf /path/to/bent.tar)

where the only purpose of the subshell is to preserve the current directory in the main shell.

Do you know the history of this .tar file?

Was it created on this system? If so, using what command?

If 'gtar' is installed on your system I would definitely just try substituting 'gtar' instead of 'tar' on the command line(s) and see what happens.

Many times I've had 'gtar' read a tarball that 'tar' couldn't read (properly).

Just a thought.

Actually the problem is in the -C option of tar.
Code:
     -C directory file       Performs a chdir (see cd(1))  opera-
                             tion on directory and performs the c
                             (create) or r (replace) operation on
                             file.  ...

You are using eXtract which is not supported by the -C option. As far as I can see there is no equivalent option for extracting to a particular directory.
