The temp directory located in /var/opt/novell/sentinel/tmp is taking several GB of space and need to clean it up. Does any of you know if it's safe to delete the content of this directory? Some files/sub-folders are more tan 18GB.

Some files and folders are like these:
+~JF7761283050944562779.tmp (file)
esec-tmp-mgr-6120500159591330096.tmp (folder)

Thanks in advance for your input.
