Make Parallel Jobs

[Bill Harding <bharding at amazeent dot com>]

All,
 
I have been combating a make bug for several months, and 
after many hours of web searching, I am finally breaking 
down to see if anyone might possibly have some idea about 
what I can do about this bug.  The issue is that I am 
building assets for a video game using the following command:
 
make -C Anims --no-print-directory -r -f Anims.mk all &&  
make -C BGs --no-print-directory -r -f BGs.mk all 

However, at seemingly random intervals throughout the build 
process (usually about 4-5 times per build), I get the 
following error:
 
make[1]: *** read jobs pipe: No such file or directory.  Stop.
make[1]: *** Waiting for unfinished jobs....
ShIdleA.ica
make[1]: *** Waiting for unfinished jobs....
make: *** [build] Error 2
Error executing c:\windows\system32\cmd.exe.
 
After I get this error, I can invoke the build again and 
it will start building files again where it had left off, 
indicating that there was no problem with the asset itself.  
The most perplexing part of this "jobs pipe error" is that 
I am not using jobs.  Even if I explicitly pass make a -j1 
flag, it still gives me this error quite often, and 
cumulatively this ends up being an enormous time cost.  
Do you have any idea why I would be getting this error 
when I am not using jobs, and more importantly, if there 
is anything that could be done to fix it?
 
Thanks!
