The problem has been identified and fixed in 6.4.0svn, 6.5.svn and 7.svn. It was a memory leak where memory was allocated but not released: My test: Spearfish, using valgrind: v.net.visibility input=roads output=graph Original memory leak: ==3746== LEAK SUMMARY: ==3746== definitely lost: 18,522,763 bytes in 661,297 blocks. ==3746== indirectly lost: 396,532,048 bytes in 991,328 blocks. After fix: ==16713== LEAK SUMMARY: ==16713== definitely lost: 7,660 bytes in 44 blocks. ==16713== indirectly lost: 3,624 bytes in 8 blocks. There is still a tiny loss somewhere in the vector library but that's marginal (and released when the module exits). Options for you now: - update and compile from SVN - ask someone to compile for you :) - wait for the next release of 6.4.0. Thanks for reporting this. Ah, please report later if it now works for you.
