2 ucc-bin processes for 1 server?

[th0u]

Hello,

i setup a linux-server with ut2004-dedicatedserver-3339.
When starting the server with ucc-bin server [game/type] the server starts normally and it spawns second instance of itself.
So i have 2 ucc-bin in processlist.

I wonder if this a normal behaviour.

11652 pts/2 S< 0:24 ucc-bin server DM-DE-Osiris2?...
11655 pts/2 S< 0:00 ucc-bin server DM-DE-Osiris2?...

TIA.

yes, the 2nd process hardly does anything. It's only use for non-blocking DNS lookups (needed to reslove hostnames for the masterserver and stuff.)

thx for the response.

Hardly does nothing and yet doubles the memory used. What a waste, that is really bad!

It doesn't use double the memory, it's a CoW image so all static data and text segments are shared.

It would be a waste if it was actually true.

Threads share memory space, processes don't. Threads only have their own process time. So in the `ps` listing you will always see the same ammouth of memory being used by all threads of a process.

Use the -m or -f switches to see a better representation of the processes. Particularly -f.
