Do all of your servers fail all of the time or do some fail some of the time? What do the ones that fail have in common and how do they differ from the ones that do not fail? If you have the option to try alternative kernels on the servers that exhibit this behavior I'd suggest that might be a good next step. > > > > > Am Sa., 14.

Looks likely that the kernel did not have enough entropy by then. Is the system not connected to a keyboard? Or it was just booted? If that’s the case, probably you could wait a while before try to launch mgr or use the ceph command line utility. >>> >>> >>> >>> > >>> > ``` >>> > # gdb --args /usr/bin/python3.7 /usr/bin/ceph -s >>> > GNU gdb (Debian 8.2.1-2+b3) 8.2.1 >>> > Copyright (C) 2018 Free Software Foundation, Inc. >>> > License GPLv3+: GNU GPL version 3 or later <http://gnu.org/licenses/gpl.html> >>> > This is free software: you are free to change and redistribute it. >>> > There is NO WARRANTY, to the extent permitted by law. >>> > Type "show copying" and "show warranty" for details. >>> > This GDB was configured as "x86_64-linux-gnu". >>> > Type "show configuration" for configuration details. >>> > For bug reporting instructions, please see: >>> > <http://www.gnu.org/software/gdb/bugs/>. >>> > Find the GDB manual and other documentation resources online at: >>> > <http://www.gnu.org/software/gdb/documentation/>. >>> > >>> > For help, type "help". >>> > Type "apropos word" to search for commands related to "word"... >>> > Reading symbols from /usr/bin/python3.7...Reading symbols from /usr/lib/debug/.build-id/99/21c75e6930d3e9d9fa8c942aca9dc4500bb65f.debug...done. >>> > done. >>> > (gdb) run >>> > Starting program: /usr/bin/python3.7 /usr/bin/ceph -s >>> > [Thread debugging using libthread_db enabled] >>> > Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1". >>> > >>> > [New Thread 0x7fffed515700 (LWP 30323)] >>> > [New Thread 0x7fffe7fff700 (LWP 30324)] >>> > [New Thread 0x7fffe77fe700 (LWP 30325)] >>> > [Thread 0x7fffed515700 (LWP 30323) exited] >>> > [New Thread 0x7fffed515700 (LWP 30326)] >>> > [Thread 0x7fffe7fff700 (LWP 30324) exited] >>> > terminate called after throwing an instance of 'std::runtime_error' >>> > what(): random_device::__x86_rdrand(void) >>> > >>> > Thread 4 "python3.7" received signal SIGABRT, Aborted. >>> > [Switching to Thread 0x7fffe77fe700 (LWP 30325)] >>> > __GI_raise (sig=sig@entry=6) at ../sysdeps/unix/sysv/linux/raise.c:50 >>> > 50 ../sysdeps/unix/sysv/linux/raise.c: No such file or directory. >>> > (gdb) >>> > (gdb) bt >>> > #0 __GI_raise (sig=sig@entry=6) at ../sysdeps/unix/sysv/linux/raise.c:50 >>> > #1 0x00007ffff79de535 in __GI_abort () at abort.c:79 >>> > #2 0x00007fffeddb8983 in ??
