Please kill the lttng-sessiond that is already started (the one with -d). Instead of that one, run the sessiond with: lttng-sessiond -vvv (don't run lttng-sessiond -d before) Thanks, Mathieu > > > > > Thanks in advance, > Pavan > > -----Original Message----- > From: Mathieu Desnoyers [mailto:mathieu.desnoy...@efficios.com] > Sent: Friday, June 08, 2012 11:12 PM > To: Pavan Anumula > Cc: lttng-dev@lists.lttng.org > Subject: Re: [lttng-dev] Lttng start failed > > * Pavan Anumula (pavan.anum...@sasken.com) wrote: > > Hi , > > > > I am new to LTTng usage, I am trying to use LTTng 2.0.1 and > > LTTng-modules-2.0.2 for ARM(omapL138), with Linux kernel 2.6.33 wit RT-29 > > patch on it. > > > > After enabling all the kernel events I am facing the below errors.
