Hi all,
The perf mem report tools shows me a warning before printing results:
Failed to open /tmp/perf-8741.map, continuing without symbols
Then it seems that all the memory accesses which source address (Data
Symbol field in perf mem rep output) is located in the heap of the
profiled process is reported as "perf-8741.map" in the Data Object
field.
I am not sure to understand what this file is, what it should contain,
and why it's not created when my process is profiled ?
Moreover, I am wondering what perf mem could report for heap data
object in addition to the fact that the object is in the heap ?
Thanks,
-------

Hi,
I am again wondering why I have this issue about /tmp/perf-pid.map file.
Can anyone explain why it's not there and what this file should contain ?
Thanks,
