The key clue here is the following error message.

   Maximum number of clients reached

This is a message that the X11 server is no longer accepting
connections, usually because its resource database is full.  This can be
caused by malfunctioning software that asks the X11 server to load
resources, but does not properly ask for them to be freed.  That cause
would be consistent with the symptoms you describe, although logging out
from the desktop session kills the X11 server so it should resolve the
problem.

I would suggest the next step for you is to install the xrestop package
and run that program in a terminal window when starting a session,
monitoring its output from time to time.  This should give you an idea
of which application might be grabbing and not relinquishing X
resources.

Title:
  Unable to launch programs ~18 hours post reboot

Status in “unity” package in Ubuntu:
  New

Bug description:
  I have had a ongoing problem where programs fail to start once my
  machine has been active for 18 to 24 hours.  A reboot corrects the
  problem but it will reoccur once the waiting period has passed.  I
  reported this under bug # 1354929 but received no response.  I've been
  using Ubuntu for about 6 months so I'm still learning and this is the
  first bug I've tried to report.

  Running 14.04 with all maint current.  Hardware is a IBM ThinkCenter
  8213 with 2GB ram, 64GB SSD primary, 1 TB data area (which is a
  windows formatted drive via USB and external case).  Dual monitors
  (one running off a graphics card, the other running off motherboard).

  Symptom Details:
  Following a boot of the machine, all software functions as it should.  All programs start fine, no issues.  After an extended idle time (I have no time limit set for session, so it doesn't even lock the screen or logout), when I attempt to start a program it will fail to launch.  This behavior is the same for all applications - Thunderbird, Firefox, Libre Office, Wine installed programs, Rythymbox, Terminal.  No error messages are presented.  All that occurs is the cursor switches to the waiting clock for 6-8 seconds then returns to a pointer.  All currently open applications function normally with one exception.  If I use an open Firefox window to go to YouTube, it will not initialize the video box.

  I've been researching how to get this reported (since my first attempt did not garner any interest).  I discovered ubuntu-bug.  So I started a new tactic.  Following a reboot, when things are working well, I open a terminal, a gedit window, and a firefox window containing a number of tabs containing the bug reporting pages I have found.  Once the failure occured, I went to the open terminal and issued ubuntu-bug unity.  The following occured in the terminal:
  ken@OurVeranda-Linux2:~$ ubuntu-bug unity
  Maximum number of clients reached
  ** (apport-gtk:13395): WARNING **: Could not open X display

  (process:15687): GLib-CRITICAL **: g_slice_set_config: assertion
  'sys_page_size == 0' failed

  A prior event generated a large number of messages indicating
  something about a key failure in apport-gtk.  That is why I setup the
  gedit window, so that I could save those messages.

  Attempted workarounds (other than a reboot):
  Logging off and back on does not work.
  Starting programs from the terminal window does not work.
  Trying to start programs from the search panel (as opposed to attempting to start from the task bar) does not work.
