I started getting a lot of errors like
rsync: failed to open
"/tftpboot/moniscreen/usr/src/linux-headers-2.6.24-19-generic/include/config/fs/posix/acl.h",
continuing: Too many open files (24)

after I upgraded from rsync 3.0.3pre2 to 3.0.0pre3. I invoke rsync on a debian
stable system on x86 with the following arguments/environment:
execve("/usr/bin/rsync", ["rsync", "--numeric-ids", "--delete",
"--delete-after", "-ax", "[EMAIL PROTECTED]:/", "/tftpboot/moniscreen"],
["SHELL=/bin/bash", "TERM
=screen", "USER=root", "http_proxy=http://proxy.kurp.hut.fi:3128/";,
"SUDO_USER=lindi", "SUDO_UID=548", "ftp_proxy=http://proxy.kurp.hut.fi:3128/";,
"PATH=/usr/local/sb
in:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/X11R6/bin"...,
"PWD=/root", "EDITOR=/home/lindi/bin/editor", "SHLVL=1",
"SUDO_COMMAND=/bin/bash backup2 --stdin",
"HOME=/home/lindi", "LESSCHARSET=latin1", "LOGNAME=root", "LC_CTYPE=fi_FI",
"SUDO_GID=500", "_=/usr/bin/strace"])
and with the following ulimits:
core file size (blocks, -c) unlimited
data seg size (kbytes, -d) 1004140
max nice (-e) 0
file size (blocks, -f) unlimited
pending signals (-i) unlimited
max locked memory (kbytes, -l) 1004140
max memory size (kbytes, -m) 1004140
open files (-n) 1024
pipe size (512 bytes, -p) 8
POSIX message queues (bytes, -q) unlimited
max rt priority (-r) 0
stack size (kbytes, -s) 4096
cpu time (seconds, -t) unlimited
max user processes (-u) unlimited
virtual memory (kbytes, -v) 1004140
file locks (-x) unlimited
I could raise ulimit of open files but shouldn't rsync cope just fine with the
default limit?
The diff between pre2 and pre3 is quite small but I was unable to figure out
anything obvious. What extra info should I provide? The whole strace output is
96 megabytes and contains sensitive data. I was unable to reproduce the issue
with a simple
mkdir a
for i in `seq 1 4096`; do echo > a/$i; done
rsync --numeric-ids --delete --delete-after -ax a/ b
