Hi,
 
I have two problems related to (I guess!) ext_select(). Here are the descriptions of both.
 
1. I set the timeout for ext_select() and call it. Normally, messages are coming to the listening socket. This is a piece of the code:
timeout1.tv_sec  = 0;
timeout1.tv_usec = 100000; //100 ms
       
#ifndef NO_RSP
    result = rspSelect(n1 + 1, &readfdset, NULL, NULL, &timeout1);
#else
    result = ext_select(n1 + 1, &readfdset, NULL, NULL, &timeout1);
#endif
After many repetitions with different timeout values, I concluded that ext_select() wake-up is always caused by the timeout and not by data arrival. Why is it so?
 
 
2. I do the same as above, but now there are no incoming messages at all. After some time, perhaps about 10-15 minutes later, the following is reported on the screen.
Nov 15 12:36:42  iris  /kernel: swap_pager: out of swap space
Nov 15 12:36:42  iris  /kernel: swap_pager_getswapspace: failed
After this, the whole X-session crashes. I suppose that again the problem is with ext_select().
 
Best regards,
Marjan
