  34 <PRE>I restarted services with httpd disabled, to see if that helps. but the
  35 problem persists :-(
  36
  37 /proc/sys/fs/file-nr gives me 1864    136     4096
  38 so only 136 in use...
  39
  40 I did notice this in the log when restarting Services:
  41
  42 [Jun 05 13:25:12 2002] IRC Services 5.0pre1 starting up
  43 [Jun 05 13:25:13 2002] sockets: [v]sockprintf() with NULL socket!

  53 &gt;<i> OK, I've done a touch more research on this, the Linux default is
  54 </I>&gt;<i> maximum 1024 FDs per process, and 4096 in total. A `cat
  55 </I>&gt;<i> /proc/sys/fs/file-nr` will tell you the number of open FDs, the
  56 </I>&gt;<i> number in use, and the maximum limit.
  57 </I>&gt;<i>
  58 </I>&gt;<i> To increase the maximum number of FDs to 65536 (for a 2.2 kernel - I
  59 </I>&gt;<i> think 2.4 is the same):
  60 </I>&gt;<i>
  61 </I>&gt;<i> 1. In /usr/include/bits/types.h change the &quot;#define __FD_SETZISE
  62 </I>&gt;<i> 1024&quot; to &quot;#define __FD_SETSIZE 65536&quot;
  63 </I>&gt;<i> 2. Do the same in /usr/include/linux/posix_types.h
  64 </I>&gt;<i> 3. Recompile your kernel
  65 </I>&gt;<i>
  66 </I>&gt;<i> The following steps need to be performed every time you start the
  67 </I>&gt;<i> FD-hungry application, or in your init scripts:
  68 </I>&gt;<i>
  69 </I>&gt;<i> 4. echo &quot;65536&quot; &gt; /proc/sys/fs/file_max
  70 </I>&gt;<i> 5. echo &quot;196608&quot; &gt; /proc/sys/fs/inode_max
  71 </I>&gt;<i> 6. ulimit -HSn 65536
