Hi,
I'm running Fedora rawhide since Fedora 11 beta, and everything worked
fine until recently. Now, if I run a session for a few days (I generally
don't log out, I suspend my laptop), after some time, I can't run any X
application anymore. I get the message:
Maximum number of clients reached
If I close some applications, I can continue for some time until the
error triggers again. Then, I have to log out, and start a fresh session.
If I use xlsclients, (after closing an application I'm quite sure
doesn't eat up all connections to the X server, like gmpc), I don't get
such a huge list. Now for example, I get:
$ xlsclients | wc -l
44
From http://www.x.org/wiki/Development/X12 I can see there is a limit of
256 clients. I hardly reach the limit. But starting xterm for instance
is sufficient to trigger the error again.
Do you have any idea where I can gather information to know which
application is responsible?
As a side note, I'm using the RPM Fusion repository as well (we don't
have software patents in Europe, and I hope it'll stay this way). I also
have the flash player installed (I heard that troubles can come from
there). But I don't think this is the cause of the problem as I don't
visit that often sites containing flash. And the errors happens anyways.
Thanks.
Mildred

Check the output of 'sudo lsof -p `pidof Xorg`' when this happens. This
will show you what file descriptors are in use by the X server. Last I
checked this error message was misleading, and could mean either "I've
hit the client limit" or "I've run out of file descriptors".

That would be:
su -c lsof -p `pidof X`

Hi,
So, it happened again. There are 234 opened sockets, and the last file
descriptor seems to be 255u, so perhaps there is a limit there. Any
ideas on how to find the program responsible for that?
Thanks.

Hi,
So, it happened again. There are 234 opened sockets, and the last file
descriptor seems to be 255u, so perhaps there is a limit there. Any
ideas on how to find the program responsible for that?
The 'u' just means the file is opened read/write. The actual fd number
is 255, which is certainly suspicious. Just for kicks, try 'ulimit -n'
to see if your open file limit is set too low for some odd reason.
You can also check the open socket numbers using netstat, e.g.
netstat | grep <sock-number>
will give an idea of what the file is.

to see if your open file limit is set too low for some odd reason.
It's not that suspicious :o) look for XFD_SETSIZE and MAXCLIENTS in the
X server source code. It's still a hardcoded limit in the server.

Well on my system the above incantation gives over 1200 open files, and
I'm assuming we're all using the same X server since it's F11-pre or
similar.

This is a bit awkward since there's no obvious way to get the inode of
the peer socket. The best you can do is hope that it was created
immediately before the corresponding fd in the X server. So, something
like this:
---
#!/usr/bin/python
from subprocess import Popen, PIPE
client_sockets = []
match = 0
ns = Popen(["netstat", "-an", "--unix"], stdout=PIPE)
output = ns.communicate()[0]
for line in output.split('\n'):
if line.find("X11-unix") != -1:
match = 1
elif match:
match = 0
inode = line.split()[6]
client_sockets.append(inode)
lsof = Popen(["lsof", "-U", "+c0", "-w"],
stdout=PIPE)
output = lsof.communicate()[0]
for line in output.split('\n'):
try:
inode = line.split()[7]
if inode in client_sockets:
print line
except:
pass

Thanks a lot, I used a similar shell script:
#!/bin/sh
inodes="$(netstat -an --unix | grep X11-unix | sed 's/ */ /g' | sed
's/\[ ACC \]/[ ]/' | cut -d' ' -f7)"
lsof +c0 | head -n 1
while read line; do
inode="$(sed 's/ */ /g' <<<"$line" | cut -d'
' -f8)"
#echo $inode
if grep "^$inode$" <<< "$inodes" >/dev/null; then
echo "$line"
fi
done <<<"$(lsof +c0 -w | tail -n +2)"
I removed the -U option of lsof, with it I couldn't find anything
I found a lot of instances of syndaemon, I think it's the cause.

Well, thank you. I haven't gotten this issue back. So maybe it has
resolved itself :) But I'll try if that happens. But it just shows all
open file descriptors of Xorg, I'm just no sure how I can see what's
wrong with just this command. But I'll ask then.
Thank you.

Hi,
I'm running Fedora rawhide since Fedora 11 beta, and everything worked
fine until recently. Now, if I run a session for a few days (I generally
don't log out, I suspend my laptop), after some time, I can't run any X
application anymore. I get the message:
Maximum number of clients reached
If I close some applications, I can continue for some time until the
error triggers again. Then, I have to log out, and start a fresh session.
If I use xlsclients, (after closing an application I'm quite sure
doesn't eat up all connections to the X server, like gmpc), I don't get
such a huge list. Now for example, I get:
$ xlsclients | wc -l
44
From http://www.x.org/wiki/Development/X12 I can see there is a limit of
256 clients. I hardly reach the limit. But starting xterm for instance
is sufficient to trigger the error again.
Do you have any idea where I can gather information to know which
application is responsible?
As a side note, I'm using the RPM Fusion repository as well (we don't
have software patents in Europe, and I hope it'll stay this way). I also
have the flash player installed (I heard that troubles can come from
there). But I don't think this is the cause of the problem as I don't
visit that often sites containing flash. And the errors happens anyways.
Thanks.
Mildred
Well, it seems the best way is to:
lsof | grep libX11.so
I tried the -p --program option of netstat (netstat -anpx | grep
X11-unix), but it doesn't display anything for the X11 socket. I also
tried to match the inode displayed by netstat to a program using lsof
without success. If I try a find -lname '*socketnum*' /proc, no luck either.
So ...
And it seems syndaemon (synaptics daemon that block the touchpad while
we use the keyboard) is responsible.
thanks everyone
