Public bug reported: I had read good things about jemalloc so I decided to try it out on an Ubuntu 12.04 system.
apt-get install libjemalloc1 set /etc/ld.so.preload to /usr/lib/libjemalloc.so.1 restart apache Apache crashed quickly and this was in the logs: [477629.499581] show_signal_msg: 2 callbacks suppressed [477629.499586] apache2[20748]: segfault at 7fa399400000 ip 00007fa3979e6e01 sp 00007fff142a63d0 error 4 in libjemalloc.so.1[7fa3979e3000+18000] ** Affects: jemalloc (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1152793 Title: Segfault preloading jemalloc with apache on Ubuntu 12.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/jemalloc/+bug/1152793/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
