Strange, haven't seen that error message before.
Instead I'm seeing this:
 faultString: org.perfsonar.service.commons.exceptions.SystemException: 
[unknown]: RRDStorageManager.rrdFetch: Cannot connect with rrdjtool native 
library: no jrrd in java.library.path

 Anyway, I'm running into this problem that LD_LIBRARY_PATH is getting 
removed "by itself" out of the environment.
I've added an export 
LD_LIBRARY_PATH=/usr/local/lib:/usr/local/rrdtool/lib:/usr/local/perfSONAR-1.0/contrib/rrdjtool/build
to the tomcat startup script, maybe that helps.

It's working again right now, but I have no idea for how long.

Regards,
Chris
