Hi, the log messages are misleading at best, when reproducing in autopkgtest in a local VM I've found:
$ sudo /usr/sbin/tgtd -f tgtd: iser_ib_init(3431) Failed to initialize RDMA; load kernel modules? tgtd: work_timer_start(146) use timer_fd based scheduler src/tcmalloc.cc:333] Attempt to free invalid pointer 0x55abdf028b00 Aborted It is only glusterfs, as this resolves the issue: $ sudo apt remove tgt-glusterfs $ sudo /usr/sbin/tgtd -f tgtd: iser_ib_init(3431) Failed to initialize RDMA; load kernel modules? tgtd: work_timer_start(146) use timer_fd based scheduler tgtd: bs_init(387) use signalfd notification This sounds very much like https://bugs.launchpad.net/ubuntu/+source/glusterfs/+bug/1950777 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=999700 Reported the same to Ubuntu under https://bugs.launchpad.net/debian/+source/glusterfs/+bug/1951126 and hoping to find some time for it tomorrow. -- Christian Ehrhardt Staff Engineer, Ubuntu Server Canonical Ltd
