<tt>Hi, Dawid!<br>
<br>
I think the error appears when the Networking send buffers are
full. If your system has enough resources, you can try to increase
the memory used by the buffers[1].<br>

<p><tt>Hi Dawid,</tt></p>
<p><tt>This seems to have been fixed a long time ago [1],
so I'm a bit puzzled. Just to be 100% sure, can you
try to locate the exact binary path your OpenSIPS
service is running on, and figure out the exact
version that way? (e.g. output of
"/usr/local/sbin/opensips -V")<br>

<div>I am also using rest_client - for each call,
before being proxied, an http request is made by
rest_client. Before and during this time the
http server was overloaded and took quite long
time. I am suspecting that this is linked to it
but would like to understand how exactly.</div>
