<p class="MsoNormal">The call back <span style="font-size:10.0pt;font-family:"Courier New"">
handle_close() </span>should be invoked when we remove handler with NULL_MASK. In one of the use case this doesn’t happen and our application is hanging as in attached call stack<o:p></o:p></p>
<p class="MsoNormal">and we don’t see that call back gets invoked at these times(When app hangs)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Changing the reactor mask type to <b><span style="font-size:10.0pt;font-family:"Courier New"">DONT_CALL
</span></b>has fixed this issue. I don’t see hanging any more . Can you please let me know what happens in background when the reactor type is NULL_MASK and the reason for app hang?<o:p></o:p></p>
<p class="MsoNormal">Does this wait for any process mutex to invoke handle_close callback.?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">When we use DON’T_CALL instead NULL_MASK it solved the issue but we need to know what’s the issue in depth. Please let us know if you have any information on same<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks in advance<o:p></o:p></p>
