<div dir="ltr"><div><div>Hi Igor,<br><br>Yes, it's caused by lack of shm.<br><br>I don't know if there is a proper shm value. Depending on how many modules are loaded on kamailio and how much shm a module might use over time, more or less shm should be used. In your particular case, depending on how much userblacklist table should grow, you should adjust the startup shm value.<br><br></div>Thank you for your detailed feedback on the segfault; the fix it's on its way and will be backported.<br><br></div>Stefan<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Jan 22, 2016 at 1:12 PM, Igor Potjevlesch <span dir="ltr"><<a href="mailto:igor.potjevlesch@gmail.com" target="_blank">igor.potjevlesch@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div bgcolor="white" link="blue" vlink="purple" lang="FR"><div><p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Verdana",sans-serif;color:#1f497d" lang="EN-GB">Hi Stefan,<u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Verdana",sans-serif;color:#1f497d" lang="EN-GB"><u></u> <u></u></span></p><p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Verdana",sans-serif;color:#1f497d" lang="EN-GB">Indeed, It looks to be the issue. <u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Verdana",sans-serif;color:#1f497d" lang="EN-GB">But, the root cause is the lack of SHM memory, isn't it?<u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Verdana",sans-serif;color:#1f497d" lang="EN-GB"><u></u> <u></u></span></p><p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Verdana",sans-serif;color:#1f497d" lang="EN-GB">Actually, Kamailio is running with 256M of SHM (-m 256).
