What to do when autobuilders might run out of memory when building a package
Hi,
recently I uploaded seqan and I admit I fail to build the package on two
of three machines I control and use to build. Only one of these three
amd64 machines has a big enough memory and does not die from swapping.
When looking at the build log of i386:
https://buildd.debian.org/status/fetch.php?pkg=seqan&arch=i386&ver=1.4.1-3&stamp=1390975155
I see
...

When looking at
https://buildd.debian.org/status/package.php?p=seqan
it seems that only the "more powerful" architectures are able to build
this package but also kfreebsd-amd64 fails (with a different error but I
suspect the same problem). I would consider excluding some
architectures but the package is really used on i386 and I wonder whether
there are some options to get it builded at least for this architecture.
Kind regards
Andreas.
