version 1.7.26(0.271/5/3) Couldn't acquire sync_proc_subproc


Sometimes (multiple times a day) cygwin is simply freezing and I'm
unable to enter any command on the terminal.

I sometimes receive errors like the following but not always (then
it's stays blocked):

1 [sig] bash 12368 get_proc_lock: Couldn't acquire sync_proc_subproc
for(5,1), last 7, Win32 error 0
1689 [sig] bash 12368 proc_subproc: couldn't get proc lock. what 5, val 1

Once it is frozen, I have to kill the bash and sh process (windows
task manager), to be able to close the windows and finally restart

The version is : CYGWIN_NT-6.1 version 1.7.26(0.271/5/3)  (gcc version
4.8.1 20130531 (Fedora Cygwin 4.8.1-1) (GCC) ) 2013-11-29 11:48

Thee informations that might help:

1) I've experienced the same problem on 32 bits and 64 bits version of
cygwin (I've tried to multiple versions)
2) My machine is a macbookpro 8,2 (64 bits) with windows (bootcamp).
And yes I have to use windows.
3)  the cygcheck in attachement

Any help would be greatly appreciated.
