Hi,
I've been running with haproxy (dev18 on Ubuntu 12.04) under load for a few
days, and then it stopped responding to most requests. Any suggestions to
help me figure out what happened?
Here's what I know:
* From my web browser, requests would time out to the haproxy server
* I have an
Hi Will!
stopped responding to most requests.
How did you recover from that condition? Restart HAproxy?
Reboot the whole VM?
When in that condition, did you see any other warnings or
errors (dmesg, etc)? How was the load and memory usage
(top, vmstat, free, uptime, etc)?
Regards,
Lukas
Hi,
I have an Amazon ELB in front of haproxy. To recover I switched away from
the haproxy server to an older Apache-based web server.
No warnings is syslog or dmesg. Load was high, around 1.5. I didn't
check memory (foolishly).
Here's a question -- which is better to use - httpclose or
No warnings is syslog or dmesg
Can you issue a show errors [1] on the control socket?
To recover I switched away from the haproxy server to
an older Apache-based web server.
So haproxy is still in a broken condition on that server?
If thats the case, you could attach strace to the process
Hi,
Unfortunately, I restarted haproxy, so show errors returns little of use.
Good to know about this command though.
root@www1-new:/var/log# echo show errors | socat
unix-connect:/tmp/haproxy stdio

Alright, since we don't know what actually happened and
there are no similar reports, we will probably not find
the root cause this time.
Next time this happens, please collect the information
I asked using show errors,
That's helpful. Hard to remember to be comprehensive at 3AM sometimes.
Any guidelines for server specs?

Hi Lukas,
Thanks for your bug report.
Sorry for not responding earlier. Actually I did not watch this
mailing list for some time.
I made a patch to fix this problem.
After applying this patch, it seems work correctly now.

Check if you have packet loss when this happens, we have seen similar
issues which were explained by AWS tech support that the IRQ of network
card of the physical machine was saturated by another customer of AWS. This
was resosurce issue.
The bigger instance you take, the more resources you will
That seems a pretty good theory. Specifically, how were you testing for
packet loss? Were you using ethtool?

ICMP echo requests from another EC2 instance in same availability zone
would show packet loss.
We could see it also from multiple monitoring nodes with Pingdom services.
The haproxy server itself would not report much errors except problems
talking to backends but nothing in dmesg or ethtool.
Hello,
have just started to explore HAProxy and am finding it amazing! As a long time

had a play around. What I have at present is the following configuration:

Thank you, it does work with your patch applied, great!
Now you are declaring error and erroffset outside #ifdef USE_PCRE_JIT,
but actually use them only inside. This causes a compiler
Hi,
I have more info on this. It seems that this problem occurs when I bring a
haproxy server up and there's already an existing haproxy server in the
peer group
-- Server A is running and handles requests
-- Server B comes up and immediately dies.
I believe if both servers are already up and

I was just wondering if you had any idea when a stable version of HA Proxy
1.5 will be released?
Thanks,
