Segmentation Fault Problems

[Sohel Shaheen Mallik]

Hi there,
         i am facing a strange problem , i have a remote server where i
ssh and store files as backup. But recently when i try to create a
directory by issuing a mkdir command it returns back with segmentation
fault message. But amazingly when i ncftp to that same server with the
same user privileges and try to create a directory at that same location
in the directory structure , the directory is created well and good.
                I am totally confused what the problem really is ..
                      any suggestions !! 
                         Thanks , Sohel
