[SR-Users] Question about debugging using `kamcmd pkg.stats`

[Daniel-Constantin Mierla]

Hello,

didn't get the time to look at the code, but pkg.stats should work also
for mi process, maybe the module doesn't do proc init callback. It needs
to be fixed in some way.

Also, for timer processes, either there is a buffer overflow and the
value of the size of an allocated packet is overwritten with an invalid
packet resulting in wrong values overall or something else is wrong in
other part for this particular process types. Anyhow, no value should be
more that the allocated pkg size.

The values are:

- used - how much memory is allocated for data
- real used - it is the value for 'used' plus the overhead of each
packet (the structure per packet that holds the length, next packet, etc
... plus the debug details like pointer to file and line for debug mode).

Cheers,
Daniel
