[Vm-dev] squeak on opensolaris 2009.06

[John M McIntosh]

Well on the iPhone flavour of OS-X I determined that if in aioPoll.c  
that if
maxFd was zero and you did the

      n= select(maxFd, &rd, &wr, &ex, &tv);

then the return value of 'n' was random junk.  This of course was a  
problem.
apple bug id 5971805, now closed in 3.x unable to recreate.

To work around it I altered the check for maxFd

   ms= ioMSecs();
  if (maxFd == 0)
	 return 0;

   for (;;)
     {

However this likely isn't your problem since you have a socket open  
for listen?
Assuming your
cf65d1d6 select   (8, 8047a50, 80479d0, 8047950, 8047948, 80f94e0) + 78
means 8 file/socket descriptors in use?


The other issue of course is if the image has the patch applied for  
the process lockup issue if the
image is running as a headless server, and you toggled the server  
mode, aka

Preferences togglePreference: #serverMode

That of course depends on what the image heritage is.
