Before doing that, I have stopped the processes with large memory sizes (firefox, thunderbird, ...), in order to get this memory freed. There were still more than 10GB of shared memory allocated in the system when gathering the data, while summing up the known users of shared memory (processes, tmpfs, IPC) added up to less than 100MB. Interpreting the allocation data is not really easy, as the resulting output is a 5.6GB sized file. And using page_owner_sort doesn't help me a lot, probably because I don't know the proper parameters to extract the needed data. Am I right that entries showing a timestamp for "free", i.e. not containing "free_ts 0 ns", relate to memory having been freed again? I have my doubts, as summing up the memory sizes of those entries will result in only about 1GB of memory being used, which is clearly contradicting the shared memory size shown. Please educate me how to use the gathered data, or where to put the file for your analysis. -- You are receiving this mail because: You are on the CC list for the bug.
