Public bug reported: - malloc sleeps continously when the mallocstress application which part of ltp package is executed in a loop. - From gdb backtrace it appears to be for a futex to be released in libc code. This is deadlock in glibc
There are some discussions going on for including this fix in next eglibc release. emails http://sourceware.org/ml/libc-alpha/2012-06/msg00648.html http://permalink.gmane.org/gmane.comp.lib.glibc.alpha/23397 http://sourceware.org/ml/libc-alpha/2012-07/msg00027.html http://sourceware.org/ml/libc-alpha/2012-08/msg00163.html http://permalink.gmane.org/gmane.linux.redhat.fedora.extras.cvs/832985 discussion in http://sourceware-org.1504.n7.nabble.com/BZ-13939-malloc- deadlock-td13648.html#none ** Affects: eglibc (Ubuntu) Importance: Undecided Status: New ** Patch added: "patch for malloc_deadlock from http://sourceware-org.1504.n7.nabble.com/BZ-13939-malloc-deadlock-td13648.html#none"; https://bugs.launchpad.net/bugs/1081734/+attachment/3440527/+files/malloc_deadlock_patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1081734 Title: malloc hangs when ltp mallocstress is run repeatedly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/eglibc/+bug/1081734/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
