Hello, We have installed a CreamCE UMD version with the GE-utils last week. We are seeing now the following issues, we don't know why but the following files are created in the /var/tmp and in the /tmp of each WN: - In the /var/tmp of each WN are created the following kind of files: jobWrapper.sh.30601.31078.1330877994 cream_017345029.e7232407 cream_017345029.o7232407 cream_957951457.pe7234101 cream_957951457.po7234101 err_cream_985174690_StandardError out_cream_009145860_StandardOutput The previous files are not deleted. In the /var/tmp of each node are also created files like: home_cream_007730080 With the following content: # ls home_cream_007730080 CREAM007730080 CREAM007730080_jobWrapper.sh cream_007730080.proxy err_cream_007730080_StandardError out_cream_007730080_StandardOutput The previous files are deleted when the job is finished. Also, in the /tmp of each WN are created the following files which are not deleted: submit-helper-20120302-110618-opssgm001-31159 sam.9968.6882 globus-tmp.compute-5-2.25785.2 Probably, this is an error in our configuration. I have configured the following variable on YAIM at the CreamCE side and apparently is also using this directory: CREAM_SANDBOX_PATH="/home_grid/var/cream_sandbox" On the other hand, the HOME for the users is shared between the WNs and Cream-CE. Other peculiarity is that we are using a gLite Tar-WN version on the WNs, so maybe the issue is due to some variable that I should have configured in the WNs. In any case, any help is welcome :) Thanks in advance, Esteban
