3300.0. "windows disappear" by CVG::ESONIS (What now?) Tue Sep 04 1990 14:29

    Hopefully someone can help with a minor problem I'm having... 
    I've been using an MV3500 running V5.3-2 decwindows. 
    Things work fine most of the time, but every so often all of 
    my decterms will just disappear. Most often it seems to happen 
    when I'm resizing a window, whether I use a "set term/wid=" 
    command, or use the customize menu. I have never been able to 
    find any trace of a process dump or information in any of the 
    decw*.log files which would point to a possible cause. 
    	Autogen/feedback has been run several times, without having
    any effect.
    
    - is there a way to trace a failure of this sort?
    
    - perhaps some applicable sysgen parameters aren't being 
    	set properly by the autogen?
    
    - Is this sort of bahaviour a known problem?
    
    Thanks for any help someone can offer....

	DECterm is probably running out of memory. You can check this by looking at the DECterm log file: define the logical name DECW$DECTERM_OUTPUT in your LOGIN.COM to be the name of the log file that you want. To give DECterm more memory, increase your PQL_DPGFLQUOTA parameter in SYSGEN. -- Bob
3300.2	io error 65535	CVG::ESONIS	What now?	`Wed Sep 05 1990 10:30`	18
	Thanks for the help.... I defined the logical, and re-started my session. Shortly afterwards, the windows disappeared... the following output log was produced: DECterm version V2.0 now at your service... To create DECterms, use the Session Manager or call the DECwTermPort() routine from another process. XIO: fatal IO error 65535 on X server "ANSON::0.0" after 562 requests (562 known processed) with 0 events remaining. Is this what I should see if more memory is needed? I'll probably add an increase for PQL_mumble anyways, and autogen again.....

	Re: .2 From the log file it looks like Xlib or the server might have dropped the connection. Is there anything "interesting" in the server log file? -- Bob

3300.5	too many events?	CVG::ESONIS	What now?	`Thu Nov 01 1990 06:38`	25
	Still haven't gotten anything from the server log, but the last time I lost my screens the decw$terminal_output.log contained the following: DECterm version V2.0 now at your service... To create DECterms, use the Session Manager or call the DECwTermPort() routine from another process. Warning: too many graphics expose events Warning: too many graphics expose events Warning: too many graphics expose events Warning: too many graphics expose events Warning: too many graphics expose events Warning: too many graphics expose events X Toolkit Error: Cannot perform calloc There were large numbers of the warning messages regarding "too many graphics expose events".... Do these mean that I'm using too many windows? If so, is there an adjustment to be made?

	Re :.5 "Warning: too many graphics expose events" is an internal error message which indicates that there is a problem in DECterm's code that handles occluded scrolling. I should probably have removed this message from the shipped version of DECterm since it is likely to confuse people. Your problem is that the DECterm controller is running out of memory. You should increase your PQL_DPGFLQUOTA parameter in SYSGEN. -- Bob
