After taking a long look at the code, it appears that ProblemReport.load() method brings everything from the report in memory. While this is acceptable for normal crashes, it becomes particularly difficult for kernel crash dumps that are often multi Gb.
Since Raring, kernel crash dumps are no longer stored in the apport report so this is not an issue. But for all kernel crashes happening on Precise, this _is_ a problem. My proposal is to add a ProblemReport.extract() method that will read the report and write the binary content to disk. A first pass is done by loading the report with binary=False. This will NOT load the binary elements of the report. Those will be identified while writing the other elements of the report and then used in conjunction with ProblemReport.extract to write only those binary content directly to a file. I will propose a merge for that shortly -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1307413 Title: apport-unpack requires too much main memory to run To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apport/+bug/1307413/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
