Jenkins Base ClearCase Issue

[Didem]

Hi all, 

I setup Jenkins in a build server using Base ClearCase plugin. For every build, plugin runs the following commands ;

$ cleartool lsview -cview -s
$ cleartool lsview "view_name"


Mostly, these commands runs OK but sporadically the command gives the following output;

$ cleartool lsview -cview -s

cleartool: Error: Unable to find view by uuid:30.4677e2345f.82da.45:cc:12:a0:8d:29, last known at "<viewhost>:<stg_path>".
cleartool: Error: Unable to establish connection to snapshot view " 30.4677e2345f.82da.45:cc:12:a0:8d:29 ": ClearCase object not found
cleartool: Error: Cannot get view info for current view: not a ClearCase object.

FATAL: Base ClearCase failed. exit code=1

I could not understand why this command gives different outputs as I stated above.
Could you please help about the possible causes of this issue ?

Thanks in advance, 

Regards
