<div>Hi there,</div>
<div> </div>
<div>I have already tried sending an email to this list, but I got no reply. As my problem is really urgent, I try again with a shorter email.</div>
<div> </div>
<div>I am doing automated traffic tests with wpa_supplicant and from time to time (sometimes after two hours, sometimes after 6 hours and sometimes not at all) I get segmentation faults.</div>
<div>I use a customized driver, maybe there is something wrong with my driver, but there might be a problem with the wpa_supplicant as well.</div>
<div> </div>
<div>Let's have a look at my debug output:</div>
<div> </div>
<div>after scanning the following occurs:</div>
<div> </div>

<div>------------------------------------</div>
<div> </div>
<div>this comes from my driver:</div>
<div>ioctl error HEOCDRIVPRIV!: Machine is not on the network </div>
<div> </div>
<div>But what does this mean? :</div>
<div>Added BSSID 00:00:00:00:00:00 into blacklist</div>
<div>...</div>
<div>Removed BSSID 00:00:00:00:00:00 from blacklist (clear)<br>Removed BSSID 00:16:9d:7c:b5:e0 from blacklist (clear)</div>
<div> </div>
<div>it seems like there are two scan requests at the same time. And this seems to lead to the segmentation fault.</div>
<div> </div>
<div>Any idea where I might start looking for a bug? Is it possible that there is a bug in wpa_supplicant?</div>
<div> </div>
<div>Please help me! I have to write my diploma thesis about this and right now I am stuck with this :-(</div>
<div> </div>
<div>Thank you!</div>
