OpenDX crashes and cannot open large networks. What can I do?
There are some known issues with sockets being too small and causing problems. This can be fixed by setting the DX_SOCKET_BUFSIZE environment variable to a number larger than the typical default of 32K. One suggested size is 262144 but different OSs may be limited. Some operating systems have a set limit for socket buffer sizes so they must be increased as well. For example, Redhat Linux sets this limit in the following two files: /proc/sys/net/core/rmem_max, /proc/sys/net/core/wmem_max. They can be increased by changing the values within these files.
