Thanks. The problematic test is TestLinuxSendfile in libgo/net/http/fs_test.go. That test binary invokes itself using strace. In the trace here, that strace fails: 8511 ptrace(PTRACE_TRACEME, 0, 0, 0) = -1 EPERM (Operation not permitted) 8511 write(2, "strace: test_ptrace_setoptions_f"..., 96) = 96 The strace is supposed to start up a little server, and the test binary tries to connect to that server. Since the server hasn't started, the test times out. The strace invocation is strace -f -q -e trace=sendfile,sendfile64 ./a.out -test.run=TestLinuxSendfileChild Any idea why that would fail? The Alpha stack trace you send also indicates a failure in this test. It could be for the same reason; hard to say. The Alpha strace output you send doesn't tell me much, since it wasn't done with -f. Ian
