I am trying to run vtssrun with apache server where one master process spawns several child processes.
vtssrun does not seem to be collecting profile data forthe child processes and I can't figure out why.
This is how I am invoking vtssrun
After the run completes, I see a lot of empty .vtss files.
gives some results but very few samples and none from the child process.
I also tried attaching to one of the apache child processes with
but it immediately exits with the below message.
Internal Error: Attached application can be terminated abnormally
Stop request has been processed..
I think trace:trace is default mode, so child process s'd be getting profiled by default. Can you please help with this ?
