[udpgw] "BConnection_Init failed" keeps spamming over and over

[PANCHO7532]

Well, i'm using BadVPN (only the udpgw module) in an VPS with too many connections over the udpgw app (the server is using Ubuntu Server 18.04.2 LTS, 1.0GB RAM) and after a while handling the incoming connections, starts spamming the following lines over and over:

ERROR(udpgw): BConnection_Init failed
ERROR(BConnection): accept failed

The problem gets "solved" when i close the app and i reopen it, but after a while starts spamming again these messages, and refuses any new connection. And this error consumes the 100% of CPU when it happens.

I execute the app with the following arguments:
badvpn-udpgw --listen-addr 127.0.0.1:7300 --max-clients 1000000 --max-connections-for-client 100000 --client-socket-sndbuf 10000000

I don't know if this is an issue or i'm executing the app in a wrong way (or would be an server resources problem)

What's your ulimit and how many connections in parallel?

[PANCHO7532]

At least 45 connections
What do you mean with "ulimit"?

Hi, 45 connections is not too much. I thought you may hit socket ressource limits as defined by: ‘ulimit -n‘

This throws me when i execute ulimit -a in console:

root@p7com-serv1:$ ulimit -a
core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
scheduling priority (-e) 0
file size (blocks, -f) unlimited
pending signals (-i) 3695
max locked memory (kbytes, -l) 16384
max memory size (kbytes, -m) unlimited

POSIX message queues (bytes, -q) 819200

max user processes (-u) 3695
virtual memory (kbytes, -v) unlimited
file locks (-x) unlimited
root@p7com-serv1:#

And with the "-n" argument throws 1024, and now, if i guess, that number means how many connections/sockets can handle per system user, but i still don't see any logic there, if only i have at least 45/50 connections per day...
...Or i am misunderstanding something in this
