XCreateColormap() for Pseudocolor 15bit fails

[Felix Schulte]

Hello,

does anyone know under which conditions XCreateColormap() can fail? I
have selected a Pseudocolor 15bit visual but calling XCreateColormap()
fails all the time:
X Error of failed request:  BadAlloc (insufficient resources for operation)
  Major opcode of failed request:  78 (X_CreateColormap)
  Serial number of failed request:  39
  Current serial number in output stream:  40

Breakpoint 1, 0x40178ab6 in exit () from /lib/libc.so.6
(gdb) where
#0  0x40178ab6 in exit () from /lib/libc.so.6

Any ideas, comments, opinions on what I am doing wrong?
