Between 30 min and 2 hours uptime, varnish indicates that one of my
backend is not healthy:

{{{
Backend name Admin Probe
boot.b1 probe Healthy 5/5
boot.vod probe Sick 2/5
boot.b2 probe Healthy 5/5
boot.b3 probe Healthy 5/5
}}}

every 5 segs this backends goes sick in varnishadm, from the first time it
is detected unhealthy CPU load rises, and varnish no longer responds to
curl.
strangely, the backend always respond to curl requests with 200 (curl in
while loop), the vod backend is nginx, and probes (/test) is the status
page.

{{{
backend vod {
.host = "127.0.0.1";
.port = "1000";
.probe = {
.url = "/test";
.interval = 5s;
.timeout = 5s;
.window = 5;
.threshold = 3;
}
}
}}}

{{{

In varnishstats, VBE was flapping, i capture every 1 seg:

#1753: Bakend flapping and High load

Comment (by phk):

First: We did change the probing code recently, so I'm not ruling out
that there may be bugs.

Try doing a "backend.list -p" CLI command, that should show you which
exact part of the probe is missing.

From the above varnishstat I can see that b1 and b2 probe flawlessly, b3
has some errors and vod has many errors.

Also, varnishlog would likely contain clues.

backend flapping: no

high load: no

varnish stop answering to curl after 30 min to 2 hours uptime.

No firewall rules.

logging method:
{{{
varnishlog -g raw > file
}}}

VSL tag "Backend_health" always shows "Still healthy" for all probes, in
all cases.

Reversing to trunk e05ac94a893090707ea95bf16578b13388917165 not show this
problem.

In vcl I do not have any status 909 (backends only responds with standars
status codes), however:

{{{
cat file|grep -w 909|grep Debug

initially, SeessClose is primary by RX_TIMEOUT, when the problem begins to
manifest, SessClose changes to RESP_CLOSE, and then only REM_CLOSE.
