Hello, I just started to use lttng. I use Ubuntu 12.04 and the kernel version 3.8.12. I use a customized kernel, so the lttng package in ubuntu can't be installed correctly. I built lttng 2.0 myself.
Then I followed the steps in https://lttng.org/quickstart. When I run lttng start, I got the errors: root@ubuntu:~# lttng start PERROR: sendmsg: Bad file descriptor [in lttcomm_send_unix_sock() at sessiond-comm.c:311] PERROR: send consumer channel: Bad file descriptor [in send_kconsumer_session_streams() at main.c:636] PERROR: ioctl start session: No buffer space available [in kernel_start_session() at kernel.c:397] Error: Starting kernel trace failed Someone said in the mailing list that this problem may have something to do with memory limit. But it shouldn't be my case as my machine has 512GB memory. Can anyone help me troubleshoot the problem? Thanks, Da _______________________________________________ lttng-dev mailing list [email protected] http://lists.lttng.org/cgi-bin/mailman/listinfo/lttng-dev
