[1.3b60 & 62] (Auto)Save failure

[wolph42]

My apologies for the lack of detailed info but I was running a campaign at a friends place on his freshly windows 7 (32) installed computer, last saturday. I've installed the latest java client and then I installed the latest MT (b62).

'After a while' (2 hours??) I all of a sudden got an error message stating something in the line of:
error java access? ??? cannot autosave.

Then I got that message every 5? minutes (I know that I could have turned it off but I was busy running the game)
At that point I saved the game several times (which succeeded) then after another 2 hours(?) all of a sudden I also got an error message stating: error saving game (cannot save game?).

We really need the error dump.

In the .maptool folder, there should be a log file. Post the stuff that pertained to that issue that day.

(hmm forgot to turn on the notify on reply, there doesn't happen to be a 'do this automatically'? )

this might take a while as its my friends pc not mine. I'll ask him though

[wolph42]

well that is a lot faster then expected...

Looking at the time codes it seems that it took 3 hours for the bug to 'occur'
What did I do in those 3 hours... with MT not that much, the players are at the table so they roll the dice and keep track of damage. I only apply damage to npc tokens, use the initiative window (internal) and copy pasted / cut pasted a couple of token from map to map, mainly the pc tokens. I switched maps roughly... 10 times. It might be that the error started to occur just after a map switch...

I can send you the campaign file if you want, but its quite big: 17Mb

What memory configuration did you run the server with? It looks like you need to run that campaign with more. MT can often fail to save when you're approaching the ceiling of the memory allocation.

The fact that you could manually save the file without error is a little odd though... maybe auto-save uses even more memory for some reason.

[wolph42]

i was considering that, but essentially that means that there is a memory leak in MT as it 'happens' after 3 hours with low intensive use.

I was running it at standard config. That is I didn't use the .bat files (as they eventually generate other errors posted also in this section). So the launcher at standard config which from the top of my head is I believe:
stack:2
memsize 256

Well, you said that the campaign was 17 megs... is that on one map? If you have multiple maps, you may have switched to one that's going to cause most of the issues later in your game.

That said, I think people have mentioned some memory leak issues more recently... though I believe at least one of the problems was supposed to have been addressed in b62.

Since you're running this on a Win 7 computer, I'm going to assume that you've got at least 2 megs in that system. Start running that campaign with Memsize: 1024. And watch the memory usage at the bottom right-hand corner. If it starts getting up into the 800's, you're probably going to need to save and reboot... you can try manually flushing the memory by double clicking on the mem-usage numbers first though to see if that helps.

We do play over a network though one gm pc and one players pc. Doesn't such a high memory size influence the speed (transfer over network)?

Nope, it shouldn't--giving MapTool a higher memory allocation just gives it more space in which to perform whatever calculations it needs to do. That won't affect the amount of time it takes to transfer information between two computers, which will be almost entirely dependent on the amount of data you need to transfer, and the speed of the network you're on.

K thnx for the tip I'll go for that next time!
