Hi,

I am tryung to buuld my package on launchpad and it fails with the following error :

Error occurred during initialization of VM Could not reserve space for ObjectStartArray make: *** [debian/stamp-poms-patched] Error 1 dpkg-buildpackage: error: fakeroot debian/rules clean gave error exit status 2 RUN: /usr/share/launchpad-buildd/slavebin/scan-for-processes ['/usr/share/launchpad-buildd/slavebin/scan-for-processes', '961882f4a62c7c2c6b189452b8a776d8635ce177']

Bulid log: https://launchpadlibrarian.net/91359812/buildlog.txt.gz
Recipe: https://code.launchpad.net/~ribalkin/+recipe/json-daily

I can build the package on my machine.
Is this is somethig wrong with package itself or build environment issue?

Thank you.
