Dear all, Sorry to bother you with another email. But I think I found the culprit for causing the "/var device is full" error:
I searched /var for big size files and found this large file "cocoon-ehcache.data" at /var/cache/tomcat/work/Catalina/localhost/_/cache-dir/ -rw-r--r-- 1 dspace dspace 958M Aug 24 13:18 cocoon-ehcache.data Then I did a quick google search on this file, I think now I can safely delete this file. I'm going to do that. Hope it will solve my problem.
