Hi,

Actually, this error means that a problem occurred *during* the 32 bit
consumer spawning process... It seems the binary was found but failed
to exec it.

Running the session daemon (lttng-sessiond) with options "-vvv
- --verbose-consumer" will help us pin down the problem.

Send me back the output, I'll be able to tell you what's going on (and
also the series of command you guys did before the enable-event).

Last thing, make sure the lttng-consumerd did not segfault (dmesg) or
any other lttng-tools component.

Thanks!
David
