Hi, I'm testing Matterhorn 1.3.1 + BigBlueButton 0.8.
I installed Matterhorn on Ubuntu 11.10 according to the procedure here:
http://opencast.jira.com/wiki/display/MH/Install+Source+Linux+(Trunk)
Launched Matterhorn as service by /etc/init.d script.
When BigBlueButton ingests recording to Matterhorn, ingest fails as follows:
java.io.IOException: Cannot run program "ln": java.io.IOException:
error=12, Cannot allocate memory

I checked FileSupport.java and found that ProcessBuilder fails to invoke
"ln" command; We should specify "/bin/ln" to invoke "ln".
I modified the source to specify external commands by absolute path, and
it works fine now. The patch is attached to this mail.
