2.6.2 rsync --daemon is not working for me

Hi!

I'm unable to write with remote rsync in daemon mode.

********* My configuration:
rsync 2.6.2
Linux 2.4.20-alt16-up (ALTLinux www.altlinux.org)
(There is owl-patch in ALTLinux-kernel)

========== /etc/rsyncd.conf ============log file = /var/log/rsync

[routers]
comment = Our Backups
path = /mnt/backup/routers
uid = archiver
gid = archiver
use chroot = true
read only = false
list = true
auth users = me
secrets file = /etc/rsyncd.secrets
strict modes = true
dont  compress  =  *
hosts allow = 127.0.0.1 
hosts deny = *.*.*.*
========== end /etc/rsyncd.conf ========
========== /etc/rsyncd.secrets =========me:itsme

========== end /etc/rsyncd.secrets =====
ls -la /mnt/backup/routers/
total 12
drwxrwxr-x    3 archiver archiver     4096 ??? 17 14:34 .
drwxr-xr-x    7 archiver archiver     4096 ??? 17 22:59 ..
drwxr-xr-x    2 archiver archiver     4096 ??? 17 14:34 tmp

*********** End configuration

Now we are running rsync-daemon:

strace -f rsync --daemon --no-detach 2>~/tmp/strace.out

and trying to upload any file:

rsync -vvv resume.txt rsync://me@localhost/routers/

or 

rsync -vvv resume.txt me@localhost::routers/

with result:
=======================================opening tcp connection to localhost port
873
Password: 
send_file_list done
send_files starting
send_files phase=1
rsync: connection unexpectedly closed (73 bytes read so far)
rsync error: error in rsync protocol data stream (code 12) at io.c(342)
_exit_cleanup(code=12, file=io.c, line=342): about to call exit(12)
=======================================
=========== /var/log/rsync ============2004/09/21 12:00:23 [8245] rsync:
connection unexpectedly closed (77
bytes read so far)
2004/09/21 12:00:23 [8245] rsync error: error in rsync protocol data
stream (code 12) at io.c(342)
=========== end /var/log/rsync ========
If uid(gid) = root, then it's working ok.

This behavior is strange for me.

P.S. Sorry for my poor English.

2.6.2 rsync --daemon is not working for me

The strace you included shows that it is the fork() call that is
returning -1 (EAGAIN).  So, you need to figure out why fork() isn't
working -- e.g. what resource it thinks is "temporarily unavailable".
