<div dir="ltr">Hi.<br><br><div class="gmail_quote"><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"><div dir="ltr"><div class="im"><br></div>The main issue is that the stack trace always contains "??", which make it impossible to find out what caused the deadlock.<br>
<br></div></blockquote></div><br><br>Just wanted to update that I tried kill -QUIT (or kill -3) and there wasn't any thread dump as a result.<br>It seems the deadlock appears so deeply, that it basically hangs even the basic routines.<br>
<br>Again, if there any way to convert these ?? symbols in GDB dump to actual function names, it would greatly help discovering the culprit.<br><br>Will appreciate any idea on subject.<br><br>Thanks. <br></div>
