Hi everybody, I have a strange issue frequently when reading /proc/xenomai/stat. I do a cat /proc/xenomai/stat and I get an "Cannot allocate memory" error. This happens typcially after I have started and terminated by application that uses a number of tasks. I am able to reproduce it deterministically... While the application is running, I can see the stat values perfectly. Here is the head output of all /proc/xenomai/* files:
