8557.1my customer has similar problemGYPOS3::EIBLReinhard Eibl @FKR, DTN 865-4027Mon May 12 1997 12:1921
Hi,

have a call with similar problem symptoms:

as 2100, DUNIX 3.2d-2 and lots of
     "X Toolkit Warning: Select failed; error code 22"
what fills up his partition.

They are displaying a 3rd party application to either VXT2000 or to PC's
running windows 3.11 and windows nt. X11 emulation used is reflexion 6.0.
Unfortunately there are constraints which prevent a test with local display.
Customer found the error probability to be higher when there is high load
on the network.

Found no hint in our databases or in the 3.2d-2 patches.

Any idea ?
Was there a solution for the problem in re. 0 ?

Any help is appreciated, thanks in advance.

8557.2Vrestore de /usrMDR01::ARANCHAMCS MadridTue May 20 1997 12:479
    Hi,
    My customer has the same problem.
    I solved it. We restore the /usr , after initialized the FS.
    The customer has Advfs filesystem for / and /usr.
    
    But I don't know why the filesystem is full.
    
    regards,
    Arancha
8557.3We've seen this and have a suggestion...DECWET::DIPIETROTue May 20 1997 18:1027
Our dxadvfs application running under 3.2 occasionally encounters this bug.  
In our release notes, we have the following suggestion:

  If you get a continuous output of 'select error 22' messages 
  from the GUI on the controlling terminal, then stop and restart 
  the GUI with the -sync option.  Eg.

  # dxadvfs -sync

  This should stop the flow of error messages.

Thought we filed a QAR on this one, but can't find a record of it.
Haven't seen this one in Steel.

More info:
  
The error message: "Warning: Select failed; error code 22" 
is coming from the file NextEvent.o in libXt.a.

Our theory is that the select error bug is due to a memory bug that
is exposed only occasionally due to the ordering of X protocol messages 
between the GUI and the X-server.  You can change the timing/order of 
X protocol messages by running the application in 'server synchronous mode'.  
This slows the application down but definitely affects the bug;  At least 
one customer now has been able to stop the message spew when nothing 
else worked.
