[B3.1][DedicatedServer] Memory leak

[om23]

As I see, SM Servers directly after starting took about 140mb of ram, after 10days running 450mb when empty.

Empty TM2 servers 70mb after restart, and after 10 days 400-500mb.


It's very strange that empty tmf servers which are running 40days without restart take 20-40mb ram, and empty tm2 stadium servers took after 10 days 400-500mb ram.

System Debian 6.0.

virt 374m / res 161m / shr 55m / mem% 15.8 / runtime 1:24.75 / tm2Stadium
don´t understand this 100%, but looks ok.
of course it looks not ok compared to tmuf!!!!

command: cat /proc/meminfo
MemTotal: 1048576 kB

ahh, btw.: do guys think this is a player issue?
I was thinking it is the packs issue.!

It is definitely a issue from the Server software which is not allocate the memory correctly I think.

Well, taht's not new..

Empty TM2 servers 70mb after restart, and after 10 days 400-500mb.

These are not sufficient infos! More important are memory usage relations to the runtime, the players online, the players fluctuation...

I have the same stats when I freshly started a server, so this is absolutely saying nothing!

probably ~10

Within that short time and that less visitors we'd expected similar stats.

[TheM]

After following this topic, I thought that it might be time to post "my own" stats here as well.
On the early morning (10:40 ) there were playing 0 players on our Canyon server.
Though, that was the procces using the most memory on the dedicated server:

Code: Select all

virt 1226M | res 1063M | shr 110M | MEM% 13.7 | ManiaPlanetServer1

The server has been running since 16-03-2013, with the players mostly situated around the evenings and weekends, with a peak on Saturday night with sometimes 50-60 players.

Serverspecifications:
CPU: AMD Athlonâ„¢ II X4 Quad-Core 4x2,3 GHz
RAM: 8 GB, DIMM (DDR3)
OS: Debian 6.0.7, 64bit

I'll come back here after Saturdayevening, to see if the playerpeak has done some damage to the memory usage.

[oliverde8]

Well I had come here earlier saying I didn't have a leak, well seems I was wrong

I have 4 empty servers all of them are using 400mb or more. I have 2 Elite 1 Melee and 1 Stadium TA.

CPU : Intel i3 2130 - 3.4 * 2
RAM : 8Gb
OS : Ubuntu 12.04.2 LTS 64 bit.

But on the other hand on my second server 1 server runing Canyon TA 100mb memory usage

CPU : intel Pentium II/III not sure 800MHZ
RAM : 256Mb
OS ; Ubuntu 10.04 LTS 32 bit.

Status:
Probably fixed since Release 2013-04-11.

Thanks Xavier!

[Bueddl]

Confirming, that the server is still leaking memory, but less than before!
