are you using the latest git hub version? there is still a memory
corruption bug in it which will break the ape server sooner or later or
produces unexpected behavior.

Hi Anthony,
I look at your suggestion to fine tune the kernel, but that's not
where I am going right now.
I was experiencing request (only from 1 connection) without any
response, but did not know what was going on. Last time I was running
loop for 100,000 simple messages sending to the server from 1
connection and it was ok the first time, but the second time it was
broke at 30,000 something.
Currently I am running more tests with 10,000 loop of 5000 messages
using 1 connection for each 5 seconds intervals, I hope it will be ok
until it finished.
I really would like to know what happened in the server if it stuck
again and maybe find some way to fix/solve it. Is there any plans to
make the logs from the APE server more verbose?
Best Regards,
Teguh Eko Budiarto

Hi,
Thanks a lot for your quick answer.
- What version are you currently stressing? (1.0 or the github
version)
I was using the 1.0, currently based on <efyx> suggestion from
irc, I am currently testing the github version and can send
30,000 messages at a time. After that, I want to test the
concurrency with a lots of user test. Thanks
You should try the 1.01dev (github). Btw what transport your
clients are using? (long polling, xhrstreaming, other?)
- Did you enabled spidermonkey module?
I haven't, should I ?
If you don't need it, no :)
I will take a look on the tune hints you suggested. I will let
you know my updates.
Cheers,

Indeed, there is some value to tune on your kernel such as :
- /proc/sys/net/core/somaxconn
- /proc/sys/net/netfilter/nf_conntrack_max
- /proc/sys/net/ipv4/tcp_*
You may also look at the rlimit_nofile value in ape.conf)
Please let me know if you find other value to tune ;)

Hi,
I was doing some load test to the ape-server using a Core2 Quad Q9505
2.83GHz machine with 4GB of memory.
When I did until 5000 requests at a time, it was fine. But, when I did
for 8000 requests at a time, the server stopped to responding, even
though my CPU load was still at 25% of full capacity. When I check the
APE server status also was still online (OK).
When I checked the log, there was no explanation about what happened
to the server. It only logged the incoming request I just restarted
the server and it can start to receive new requests again. Previous
requests was gone.
The questions are:
1. How do we calculate the server capacity for the maximum loads it
can handle?
2. APE claims can handle up to 100,000 requests in single machine, but
for mine it started to to get stuck only with 8000 requests. Did I
need to do some tuning in the settings? in which file do I need to set
the settings?
3. Log file of APE doesn't explain any information related to the
server error, is there any settings need to be change to make it
produce more detailed log?
Cheers,
additional info: below are the log content (/var/log/ape.log)
