https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=288777 Bug ID: 288777 Summary: System freezes after upgrading to 14.3-RELEASE Product: Base System Version: 14.3-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: BlueSkiesApplePies+FreeBUG@pm.me Hello - since upgrading to 14.3-RELEASE, our backup server freezes every 3-4 days. All connections hang (NFS, console, ssh). Have to reboot. I've since configured watchdogd which will auto-reboot this system now. dumpdev is set to AUTO but no crash dump is generated. As I understand it, I would need swap with enough space to handle the amount of memory the system has + 10% or so. Right now it's using the default 2GB. I've looked into options but it looks like the only thing I can do is rebuild this box entirely with more swap, which I am willing to do if that helps get this fixed. The only logs I see that might be related (or as a result of this issue) are: ixl0: ixl_process_adminq: Unable to allocate memory for Admin Queue event! ixl1: ixl_process_adminq: Unable to allocate memory for Admin Queue event! watchdog pre-timeout, WD_SOFT_LOG watchdog pre-timeout, WD_SOFT_PRINTF panic: watchdog pre-timeout, WD_SOFT_PANIC set cpuid = 0 time = 1754835209 KDB: stack backtrace: #0 0xffffffff80ba8f1d at kdb_backtrace+0x5d #1 0xffffffff80b5aa11 at vpanic+0x161 #2 0xffffffff80b5a8a3 at panic+0x43 #3 0xffffffff809a610b at wd_timeout_cb+0x6b #4 0xffffffff80b78c79 at softclock_call_cc+0x129 #5 0xffffffff80b7a445 at softclock_thread+0xe5 #6 0xffffffff80b13641 at fork_exit+0x81 #7 0xffffffff81024dee at fork_trampoline+0xe Uptime: 4d11h35m57s [reboots] The Intel adapters are installed but unused.

It serves NFS v4 mounts to our internal network. There is also a remote process that rsyncs data over ssh from ZFS snapshot dirs. It's very low load. I'm logging some additional health metrics. This is the last entry before the last reboot: last pid: 48943; load averages: 0.47, 0.43, 0.41 up 4+11:34:28 10:12:00 56 processes: 1 running, 55 sleeping CPU: 0.1% user, 0.0% nice, 0.4% system, 0.0% interrupt, 99.5% idle Mem: 69M Active, 599M Inact, 848K Laundry, 51G Wired, 56K Buf, 42G Free ARC: 41G Total, 22G MFU, 11G MRU, 1665K Anon, 1785M Header, 5221M Other 25G Compressed, 32G Uncompressed, 1.27:1 Ratio Swap: 2048M Total, 485M Used, 1563M Free, 23% Inuse PID USERNAME THR PRI NICE SIZE RES STATE C TIME WCPU COMMAND 12621 root 1 23 0 52M 37M select 28 86:50 3.66% rsync ITEM SIZE LIMIT USED FREE REQ FAIL SLEEP XDOM buf free cache: 432, 0, 11, 0, 11, 0, 0, 0 vm.kmem_map_free: 45821784064 vfs.zfs.arc_max: 0 Device 1K-blocks Used Avail Capacity /dev/mirror/swap.eli 2097148 496592 1600556 24% Otherwise, there is no spike in CPU, plenty of memory available. Nothing else as far as I can see that would be causing this. The server simply freezes and has to be rebooted. -- You are receiving this mail because: You are the assignee for the bug.home | help
