Vmaps And 64bit *nix Systems

[Auntie Mangos]

Hi,

I would like to discuss about the recent issue of Vmaps and Linux 64 bit systems.

It's been some time that simple vmaps support causes really frequent crashes (5 minutes or so) ONLY on 64 bit *nix OS.

As seen in these threads:

http://getmangos.eu/community/viewtopic.php?id=30090

http://getmangos.eu/community/viewtopic.php?id=25427

and in the main thread of *nix crash reports too:

http://getmangos.eu/community/viewtopic.p...0&start=140

it's a known fact that vmaps cannot currently be used on 64bit servers, and possible solutions given in those threads didn't work (i do not consider the downgrade of an entire OS from 64 to 32 bits as a solution, ha-ha very funny indeed.)

By my side, i can say that in revision 6359 (just pre-2.4.3) the system was stable, then, updating mangos of 100-150 revisions, the problem appeared.

Then something happened to the vmaps system, but looking throughly the SVN many times, i still can't understand where the problem might have been generated.

Someone has an idea of when and where in the code this issue could have been introduced?

Any developer is working on it, or have something in mind to fix this major issue?

Someone got a working solution, maybe with a patch on these forums?

Thanks to everyone.

You guys should try http://getmangos.eu/community/viewtopic.php?id=23805 .. It replaces a lot of code that appeared in some of the freeze/crash logs so it might help..

I can vouch for this, on more than one server I have seen crashing due to vmaps, all 64-bit.

It may have happened before that revision, though, I'm not sure. The only solution would be to disable vmaps on the main continents and only use it for BGs and instances, because that is where it is needed the most.

Or solution is compile mangos as 32bit on 64bit system... something like czech guide is there .. http://wiki.wowresource.eu/index.php/Kompi...a_64-bit_Linuxu

im using amd64 Freebsd 7.0 and have vmaps on - i dont have often crashes:

Online players: 201 (max: 261) queued: 0 (max: 0) Uptime: 1d9m28sp

Thanks for all the answers.

I'll try that patch, i see that a lot of people consider it much stable.

I hope for an implementation of that patch in SVN soon, till then i'll try with 32bit compile or with G3d patch.

I hope this thread will also aid whoever has a 64bit systems.
