In the server logs I noticed the following:

ProcessServerTravel: MH-KrallFortress110.unr?game=BarbiesWorld.MonsterHunt
This pattern of error messages is repeated for several maps, but not for all; I guess it occurs only if a player votes for a map.

The corresponding file MapVoteHistory1.ini:
MapVoteHistory1.ini
Show
[MapVoteLA13.MapVoteHistory1]
M[0]=
M[1]=AS-AutoRIP
[...]
M[510]=MH-[TB]-UnrealWorld2010
M[511]=

P[0]=0
P[1]=1

P[510]=4
P[511]=0

S[0]=0
S[1]=2903
[...]
S[510]=362
S[511]=1
LastMapIndex=511
Noticeable is that LastMapIndex is 511, and all corresponding arrays in the source code have 512 elements - I looks like the typical off-by-one programming error. (I did not dig deep into the source.) For now I have reset LastMapIndex manually to 1. Maybe my sometimes hanging server has to do with this...

Any suggestions to solve this? Perhaps there is a better map vote mutator?

You have to wrap letters again. There are loaded too many maps in a column. Some map titles having the same letter are just too many filling slots (around letter G ?). For sure some maps are being missing and nobody can vote them.

When your server is running under linux you can install a crontab script with commando "crontab -e".
In batch file you kill your ucc task and before restarting it, you automatically copy some mapvote template files with empty lists in it over the active ones.
So the server will restart with an empty mapvote history list every day.
The disadvantage of this is, one time a day the actual map will be interrupted, so I would do this at a time nobody should be on the server.

Why to not simply redefine filters to not have 600 maps in a column and 200 in other ? - Actually, your measure I'm not sure if do helps because simply maps won't get loaded properly. Beside this, lists are loaded at each travel spamming console and not loading maps so player might see 645/789 maps loaded, the rest being invisible - I know what I'm saying because I fixed such a server which was not showing Godz Maps any more because they were not being listed, issue coming from filtering. I counted how many types MH-A* MH-B*.... existed and then sharing them properly through columns.

That's all nice and beauty but does not concern the problem. If you have a look for example at MapvoteLA13's code of MapVoteHistory_INI you'll notice

Code: Select all

var() config string M[512];
and later in function AddMap() such like

Code: Select all

Y=LastMapIndex;
if ( Y >= X )
{
	M[Y + 1]=M[Y];
If LastMapIndex is above ArrayCount(M)-2, the array is accessed beyond the upper boundary, and this is the case here.

BTW: I don't use file filters but I prepare the MapListTemp.ini manually. Current count:
Listindex 1: 121 maps ("small maps")
Listindex 2: 198 maps ("medium maps")
Listindex 3: 117 maps ("huge maps")
Listindex 4: 21 maps ("new maps")
total unique map count (without list index 4): 436

In snipet, is a "X" in condition which right now I won't look for it since I haven't history issues at this moment. I will do an INI check for figuring my load.

Wait a minute: If I'm looking well there, looks like is not possible to have more history maps than global number 436+ maps unless you didn't do a proper cleaning at updating maps and you count history for map which doesn't exist any more. Duh, if I'll see such issues, history class won't be configured in INI, or READ-ONLY file will save me from any future pain. Not a big deal.

Edit: By curiosity I was looking at whatever MapVoteLA14 type which I have:

Code: Select all

function AddMap (string MapName)
{
	local int X;
	local int Y;
	local bool bFound;

	if ( MapName == "" )
	{
		GoTo JL86;
	}
	if ( LastMapIndex >= 512 )
	{
		RemoveOldestMap();
	}
......
It's like it should not be more than 512 debated... I gotta admit I miss-understood the issue first time, was not about map lists was history problem.
