<div>Hi</div>
<div><br class="">

This sounds to me a lot like your kernel is configured with a
conntrack timeout of 90m somewhere. By default the linux tcp
keepalive doesn’t kick in until 7200s (120m). This is very
common when using hardware stateful firewalls with low tcp
timeouts.</div>
<div><br class="">
</div>
<div><span style="caret-color: rgb(0, 0, 0); color: rgb(0, 0,
0);" class="">Check the
sysctl net.netfilter.nf_conntrack_tcp_timeout_established in
your host, and/or adjust the kernel tcp keepalive start
timer (</span><font class="" color="#000000">net.ipv4.tcp_keepalive_time).</font></div>
<div><font class="" color="#000000"><br class="">
</font></div>
<div><font class="" color="#000000">Also check other similar
keepalive / timeout things which apply. iptables can set the
timeout per flow, as well.</font></div>
<div><font class="" color="#000000"><br class="">
</font></div>
<div>Your environment might also have some proxy stuff going on
with different timeouts and/or keepalive timers, so you’ll
need to look in to that.</div>
<div><br class="">
</div>
<div>Almost certainly though, this is a tcp timeout in a
firewall (probably iptables).</div>
