096.4 & memory problem

[orii]

I've got a problem with Pol 096, which services 2 realms at the momment, and loads about 1500 scripts during the start.
When the server is up, operating system notifies, that memory takes away about 800MB, and when the players are connected, about 1GB, and this is where the real problem starts. Every uptime hour causes increase of occupied memory for about 100MB, in spite of almost constant number of nps's, pc's and items. In spite of all, we quickly approach 2GB memory limit (windows 2k3), and a server crushes.

I wander, if you could show me the best way of tracking that memory leak, or if I set in my boot.ini file /3GB paramter, server will achieve additional 1GB of memory, which will give us some more time to server crash.

First thing to do: Upgrade from 096.4 to 096.5 and see if there's still a problem.

there is a bug with stairs & etc
..o, and nothing about memory leak in core-changes.

I ran 096 in its various releases for over a year in test and was most impressed with the way it didn't grow in RAM usage. I could easily leave the server up for 1 week without the ram getting our of control.

I'd have to suggest it isn't the core causing your problems.

What's your problem with stairs? The height of the player has been changed a couple of times iirc. In 097 for instance I have had to raise the ceiling in a few players to allow players to walk. I can't remember if 096.6 is going to include a change for char height to fix a problem reported by CWO, but I think that's not coming out for a while, being paradoxically tied to 097 and the 097 distro being released at the same time as the 097 core.

stairs are not a problem. memory leak is a problem ;p
..and i dont know where is problem (core or script)

i just searching for a tools or advice to find where is 1GBram.

this :

or maybe, please, anyone can say - what is that:

Remaining script objectimps: xxxx

last line after shutdown.

[orii]

really noone know what is that:
"Remaining script objectimps xxx"
? :>

some screenshot
1) after restart

2) after several hours


1269884 (main memory)
1916928 (VM size)

i'm sorry to bring up this post, but did you find any solution?

[orii]

no, sorry
i think-there is still problem with packethook-memory-leak
but...without packethook my shard is totaly unplayble, i can`t test this.

1. Please check your script base for usage of AppendConfigFile!

2. Do u modifiy Config files using external applications while server is running?

[orii]

1 ) no, with AppendConfigFile i have only script "staticsexport/import/check" etc. (i don`t remember when i used this last time - meany years ago ;p - so i think it`s not a problem)
1b) i have many scripts with datafile & logfile
2) i have external aplication : this aplication have access to data/accounts.txt (r/o)

[Bracco]

that should be fine, but instead there must be some other thing that causes that high memory usage... i have the same problem, and just can't figure out what's causing this

[OldnGrey]

You can always try the crude methods.

What about on a test shard: does ram usage grow without players, if you remove the npcs files and turn off the spawner does it still grow? Can you reproduce the things that do cause ram usage to grow? Are there any situations where you can stop it growing - turn off packages etc.

I would expect RAM usage to grow slightly over time due to scripts loading and staying resident. Even unloadcfg has little effect on my RAM, certainly nothing to worry about.

Checked script.log, datafile.log?

The packet hooks in the 097 distro don't cause problems on my shard either. I guess it comes down to trying to get it to misbehave on a test shard.
