<div>There is no crash, it is only low memory and new

<div>Can you suggest what can be the resolution here ?. Do we
need a process restart to free up the memory resource ?. </div>

<p>Hello,</p>
<p>these errors do not indicate a crash,
but unability to read due to low
available memory. Did you get a crash
(kamailio stopped)? If yes, any core
file from where you can extract the
backtrace?</p>
<p>Anyhow, as hint, if you use a lot of
tls, increase the size for shared
memory, it is needed a lot there.</p>
