Compilation of Etherpad fails in an OpenVZ VE

  • 772

I’m almost giving up, this will be my last try: I try to compile Etherpad on my OpenVZ server. It’s running a Debian 5.0 as the host system, in the VE I’ve got Ubuntu 10.04. I installed Etherpad in this VE with the instructions from the official Ubuntu Wiki: https://wiki.ubuntu.com/Etherpad.

Everything runs fine until it comes to compilation. After calling bin/build.sh as described in the wiki the first steps are running fine. But then I’m running into a memory error:

java.io.IOException: Cannot run program "cp": java.io.IOException: error=12, Cannot allocate memory

Well, I understand the error message but don’t see the cause. The command free tells me that there’s plenty memory left in this VE:

             total       used       free     shared    buffers     cached
Mem:       2415236    1140872    1274364          0          0          0
-/+ buffers/cache:    1140872    1274364
Swap:            0          0          0

Beautiful. But even repeating the compilation process doesn’t bring me any further.

Any help would be appreciated.

  1. I would check OpenVZ's /proc/bc/resources to see if there are any failcounts. I've seen Java installation scripts misreport the causes of problems. The "cp" command (called by Java) may be lacking some other resource.
