[ltt-dev] Multi-second gaps in trace events

[Chad Willman]

I¹m seeing long (multi-second) gaps in trace events and am wondering if this
is a known issue.

For example, trace events shown in the viewer appear normal and then
suddenly there will be a gap of 9 seconds (varies) where it appears that a
single thread is running in user mode (green) and nothing else is happening
on the entire system in any thread for 9 seconds (no context switches, . . .
nothing).

This is an excellent tracing facility, but I can¹t rely on it entirely until
I have no gaps in the trace. Any ideas ?

I¹m running -
Lttng v 0.6.33 on Linux 2.6.18 kernel on a TI DaVinci DM6467T SOC platform
Ltt-control v 0.30
Lttv v 0.8.72
Genevent v 0.30

Regards,

CW
