Hello,

there is a command to get a backtrace from the hanging processes, refer e.g. to:

Subject: [SR-Users] Kamailio hang Issue

Hi,

We are encountering a hang issue after deploying the following code:

route(DLG_MANAGE);

if ($dlg_var(voip_id) == $null) {
    $dlg_var(voip_id) = $hdr(X-Voip-ID);
}

route[DLG_MANAGE] {
    if (is_method("INVITE")) {
        dlg_manage();
    }
}

This code includes the set_dialog_profile. We have this setup with 2 proxy servers with DMQ enabled, but the issue only occurs on one proxy.

When the Kamailio proxy hangs, no logs are written.

If you have any suggestions to resolve this issue, please help.

Thanks.
