Hi, There are a couple of additional workarounds that might be useful to add to the FAQs about checkpointing with nscd: Why do I get "vmadump: mmap failed: /var/db/nscd/[something]" in the system logs?) and java jobs: (Why do I get "vmadump: mmap failed: /tmp/hsperfdata_[user]/[pid]" in the system logs?) You can disable the nscd filedescriptor passing behaviour which confuses BLCR by adding the following options to your nscd.conf file: shared passwd no shared group no shared hosts no (The only place this seems to be documented is http://anusf.anu.edu.au/~djh900/nscd.html) The sun java runtimes can be made BLCR friendly by adding the following option when calling java: -XX:-UsePerfData This will prevent the creation of the /tmp/hsperfdata* files.
