<p class="MsoNormal">Also, how many child threads do you have for how many interfaces? Do you use TCP/TLS? We have seen that sudden increases in traffic can overload the sockets and cause backups/blocking with connection-based protocols, especially if the remote
end of a connection simply vanishes (dead peer scenario).<o:p></o:p></p>

<p class="MsoNormal">did you take network traces at the time of the fault, does the traffic get to the server?<o:p></o:p></p>
<p class="MsoNormal">if you had memory problems that would have generated logs.<o:p></o:p></p>

<p class="MsoNormal">we have a problem: sometimes, usually in an hour peaks or when the number of calls increases dramatically, by 2-3 times. the server stops responding to some SIP messages, at the same time some calls are successful. in 1-2 minutes everything
is stabilized<o:p></o:p></p>

<div>
<p class="MsoNormal">no problems were found in the logs. no ordinary message during this period is received. we assumed that there might be a problem in the memory and increase it by 2 times. <o:p></o:p></p>
