can you spot if there are any error messages in the syslog just
before the crash? It can be a buffer overflow done on the previous
packet.<br>
<br>
If you are doing some tests, maybe is better to re-compile with
'MEMDBG=1', to have details about what functions allocated the
chunks.<br>
<br>
For now, try to get the following from gdb:<br>
<br>
p *(struct qm_frag_end*)(((char*)qm) - sizeof(struct qm_frag_end))<br>
<br>
Cheers,<br>

<div> Hello,<br>
<br>
at first sight looks like a missing safety check, but I
may be wrong after a long day. I need to look a bit
deeper at it.<br>
<br>
Did you stress test it or was just casual trying? You
said it happened one, couldn't be reproduced, right?<br>
<br>
Cheers,<br>

could be related, but the issue seems to be
