Hello all,
I have a repetitive kernel panic on FreeBSD-4.9 [fresh installed from
CD - no CVS upgrades]
=========================
panic: timeout table full
syncing disks... panic: timeout table full
Uptime: 1d0h18m7s
Automatic reboot in 15 seconds - press a key on the console to abort
Rebooting...
=========================
This has happened almost once every day at random times since the
machine was put into action
There are no nasty errors or warnings in the syslog all.log/dmesg
There are no obvious patterns or chain of events that build up
beforehand
It happens when running GENERIC kernel and on different custom kernels
It happens when disks in PIO4 Mode or in UDMA mode
It happens - randomly - when busy or idle
This is the first time it as auto-rebooted - previous times it just
hangs @ syncing disks... and needs power-cycling.
The disks were in PIO4 mode for this first auto-reboot
So I will enable crash-dumps - I guess I may be able to find the
culprit with gdb
SoftUpdates anabled, ata write cache off, ata tagged Q off
maxusers=512 NMBCLUSERS=32768
I have read about these timeout panics in 'man crash' and looking at
the kernel source, a timeout can be called by many things and that when
there are none free, it panics :(
I have worked out the value of ncallouts on my system its:
ncallout = 16 + maxproc + maxfiles;
= 73764 16 + 8212 + 65536
* [Q] Does anyone know what are the likely reasons that would case BSD
to runout of timeouts/ncallouts - 73764 worth?
man 9 timeout: timeout -- execute a function after a specified length
of time.
* [Q] ??: either the number of free ncallouts is depleating over time
or something has stopped responding, causing a rapid increase in the
number of timeouts called or something has stopped clearing its timeout
handles - a bad driver?
* [Q] Does somebody know of a method to ask the kernel how many
timeouts are assigned and what called them?
To be able to find out how many are left/being used and therefore
workout the rate of depletion would be helpful in debugging - AND to
'throw in the towel' and reboot safely before it dies!
Can this be done? [some inquiry code or a kernel patch]
Is there something already in FreeBSD that can do this?
The only quirk i see at boot is this in dmesg:
pci0: <unknown card> (vendor=0x8086, dev=0x24c3) at 31.3 irq 7
And sometimes (note: not all the time) this message after boot or
midway thru the day:
stray irq 7
* [Q] This unknown card at irq7 I imagine from vendor this is the
onboard Intel SMBus/I2C bridge. Could this play a part in this timeout
panic?
* [Q] is my kernel config at fault? (though GENERIC still paniced)
* [Q] I have a 70 gig UFS+S filesystem (27067418 used inodes) is it
normal for it to take an hour to fsck after the panic?
I welcome suggestions to debug/fix this and i can supply more info it
it helps
ells...
