... each time a client makes a [HTTP] request, Valgrind complains "Error accepting connection: Function not implemented" and my program fails to handle the request as a result.
Which versions of each of these pieces are you running: Libmicrohttpd, valgrind, hardware architecture, OS? Please give the exact copy+paste of the invocation of valgrind that fails, together with the output from Terminal that surrounds the complaint "Error accepting connection: Function not implemented". Please run under /usr/bin/strace, and report the twenty system calls that are run shortly before the complaint: strace -f -o strace.out valgrind ./my_app args... You may wish to compare versus the output from strace on the same command but without using 'valgrind'. Then the best way to gain attention of valgrind *developers* is to put all that info into a bug report at: https://bugs.kde.org/ , and post here in the mailing list the URL of the bug report that you created. -- _______________________________________________ Valgrind-users mailing list Valgrind-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/valgrind-users
