Till I upgraded my 9front I was using a fossil server (from9legacy) on my 9front FreeBSD Bhyve system, probably 9front release Emailschaden.

Now it doesn't work anymore. Remaking the programs did not help either. The fossil server now hangs immediately after start. Neither file nor console service nodes are created.  

Are there any other users of this combi?

Interesting, and not expected; Can you get a stack trace from the Fossil process?

[cinap_lenrek]

does the old kernel with fossil binary still work?

Just tested using this script:
        
        #!/bin/rc
        
        fossil/flfmt $1
        fossil/conf -w $1 <<EOF
                fsys main config
                fsys main open -AWP
                fsys main
                create /active/adm adm sys d775
                create /active/adm/users adm sys 664
                users -w
                srv -p fscons.test
                srv fossil.test
        EOF
        fossil/fossil -f $1
        mount -c /srv/fossil.test /n/fossil

and it seems to work for me; note, I don't have a venti
set up, so I have no idea if there's anything around that
which might cause problems.

i tried it, downloading 9legacy, compiling fossil and
using the following script from ori to format a fossil
file-system:

ori → http://okturing.com/src/17908/body <-- there's the script

and fossil successfully starts up and is mounted:

term% cat fossiltest.rc 
#!/bin/rc


fossil/flfmt $1
fossil/conf -w $1 <<EOF
        fsys main config
        fsys main open -AWP
        fsys main
        create /active/adm adm sys d775
        create /active/adm/users adm sys 664
        users -w
        srv -p fscons.test
        srv fossil.test
EOF
fossil/fossil -f $1
mount -c /srv/fossil.test /n/fossil

term% dd -if /dev/zero -bs 1kk -count 100 > /tmp/test.fossil

fs file is mounted via devmnt (is not a kernel device); are you sure? [y/n]: y

Thank you for looking  after my problem.

As  Ori asked, here is a stack trace from the probably hanging thread. 

/proc/504/text:amd64 plan 9 executable
/sys/lib/acid/port
/sys/lib/acid/amd64
acid: lstk()
pread(a0=0x4)+0xe /sys/src/libc/9syscall/pread.s:6

readn(n=0x4,f=0x4,av=0x44f158)+0x42 /sys/src/libc/port/readn.c:13

read9pmsg(abuf=0x44f158,fd=0x4,n=0xfefefefe00004018)+0x25 /sys/src/libc/9sys/read9pmsg.c:14
buf=0x44f158
len=0x44eeb8
msgRead(v=0x436c40)+0x71 /sys/src/cmd/fossil/9proc.c:364

launcheramd64(arg=0x436c40,f=0x2063dd)+0x10 /sys/src/libthread/amd64.c:11

The n parameter in read9pmsg() looks weird.

FYI, I also add the fossil  conf :

fsys main config
fsys main open
fsys main
venti 192.168.44.16
srv -p fscons
srv fossil
listen tcp!*!9fs
srv -AWP fossilAWP

I run venti+fossil off of 9front git without issues (well, without issues caused by 9front ;).

Can you give a full stack trace of all threads? Happy to take a look :)

I have put a file containing the 4 lstk of 4 threads at http://pkeus.de/~wb/threads.lstk

In the meantime, I tried to use an older 9front 9pc64 kernel, but this didn't help either. 
Unfortunately, I did not make a snapshot before the last sysupdate. 

The next thing I try ,is setting up a fresh clean VM from  a distribution iso : i will report whether this fixes the problem.

Looks like it's hanging waiting for a response from venti; are you able to connect to venti directly? Did your venti or fossil config change recently? I'm not aware of recent changes to upstream venti that could cause this, but it's certainly possible, and venti and fossil are both fragile enough that i can imagine recent libc changes breaking them.

This also explains why Ori and Cinap experienced no issues, since their tests did not involve venti connections.

The venti server is in active use, e.g. for providing my backups via vacfs and vnfs on FreeBSD. 
I even checked that a 2nd fossil (this time on a Raspberry Pi4)  is working.

Solved. 

Noam was right. Restarting venti made the thing working again.
