How much memory do you have?
I have 2 GB of RAM and still getting OOM after a few days...

A few days will be interesting to debug
Next day... next kill... i have to pprof before it gets killed

Is there a way to lower the rate of TCP SYN / per second ?
Interesting, there isn't any tcp syn attacks implemented in the app because they are generally blocked by the provider. The only thing that could be treated like this is the amount of attempts to build a connection with the target. You can try using the general rate limiting to work around that but it'll decrease the overall performance of the app (--min-interval
amount of attempts to build a connection
well that's called Dial
In stoppropaganda i've implmented rate limiting https://github.com/erkexzcx/stoppropaganda#dialspersecond
Edit: Here was the PR https://github.com/arriven/db1000n/pull/535/commits/025104a97a6f98f61bb4b554ca6437a649b29119#diff-f1c4adfa861d40deef193a963cc05fe1180e22fa8d2c4195c04b40b989fba4f3R238 Yeah, this PR was a little bloated :stuck_out_tongue_winking_eye:
Yeah, there's already a rate limiting in place, I just didn't treat dial as a special case but maybe I should
@deputinizer thinking about it more, I think you can already achieve the same results with existing configuration options. There's exponential backoff present on errors which you can configure to have higher initial timeout (--backoff-timeout, default is 1 microsecond) and adapt backoff-limit/backoff-multiplier accordingly so that it doesn't spin to thousands of seconds
regarding the actual memory issue, I've been debugging todays config for couple of hours and the memory usage was only fluctuating for couple of MBs. Testing it out on my benchmark server revealed that it's possible to increase the memory usage for one of the jobs by increasing the response size from the target. We were already planning to replace that job with a more effective one, I'll update this thread once we do that
@MidnightRAT @deputinizer should be fixed now, poke me if you still encounter it

the same issue on Ubuntu VM with 2 GB RAM with latest and older db1000n builds:
Jul 16 07:13:11 azurea3 kernel: [64679.724233] oom-kill:constraint=CONSTRAINT_NONE,nodemask=(null),cpuset=/,mems_allowed=0,gl obal_oom,task_memcg=/user.slice,task=db1000n,pid=10373,uid=1000 Jul 16 07:13:11 azurea3 kernel: [64679.724243] Out of memory: Killed process 10373 (db1000n) total-vm:1549092kB, anon-rss:374 792kB, file-rss:0kB, shmem-rss:0kB, UID:1000 pgtables:1060kB oom_score_adj:0
Could you advice, please? - what syntax and value should be passed to option
-min-interval
regardless of this option's value /absent value - only help displays
Please advice or pont me any how-to with any other ways to reduce memory usage by utility in Ubuntu (e.g. with options examples, etc)
UPD:
this does not help
prlimit --pid <PID_ID> --as=<MEMORY_VALUE>
e.g. prlimit --pid 10632 --as=1024000000
++++++++++++++++ UPD & UPD: script below seems solved the problem by monitoring and re-running 'db1000n' process
until $HOME/./db1000n; do echo "'db1000n' is crashed with exit code $?. Respawning.." >&2 sleep 1 done
I've spent couple of days trying to repro this on my machine but I never got it to consume more than 500 mb of RAM. Did someone monitor the memory usage of db1000n before the oom kill? I'm wondering whether it's a leak that accumulates somewhere or some kind of very weird spike in memory usage, knowing that would help to diagnose the problem
@AlexUkr73 as for -min-interval
option something like -min-interval 5s
should work
@arriven Regarding reproducing - I've noticed it is reproduced on VMs with only 1 CPU available and 1 GB RAM (Amazon AWS)
-min-interval 5s
- tried everything but didn't expect adding letter after digit ;o)
It will be the good idea to add this statement/example to application's help
