When I start it on the command line, it starts eating up all memory until it gets killed by the oom-killer. strace looks like this: mremap(0xe64aa000, 225259520, 225263616, MREMAP_MAYMOVE) =3D 0xe64aa000 mremap(0xe64aa000, 225263616, 225267712, MREMAP_MAYMOVE) =3D 0xe64aa000 mremap(0xe64aa000, 225267712, 225271808, MREMAP_MAYMOVE) =3D 0xe64aa000 mremap(0xe64aa000, 225271808, 225275904, MREMAP_MAYMOVE) =3D 0xe64aa000 mremap(0xe64aa000, 225275904, 225280000, MREMAP_MAYMOVE) =3D 0xe64aa000 mremap(0xe64aa000, 225280000, 225284096, MREMAP_MAYMOVE) =3D 0xe64aa000 ... I am in the very difficult process of moving away from that particular lega= cy=20 but this will take time. Also I'm concerned about other old binaries that m= ay=20 stop working. Any idea what is going on?
