Thanks for the answer. The bug[1] seems to have caused the pain.
I do not know what you mean by saying "This behaviour probably
highlights problems in your network infrastructure or instability of the
repository manager." If the pom not being in the repo causes m2e to
search in the external repo why does that highlight a problem in our
network infrastructure? In the mentioned case, the central repo was slow
and querying it because of the missing pom caused the hang.

There is a bug in the version of maven embedder used by m2e, it always
checks missing pom.xml files from all remote repositories (i.e.
multiple times per embedder invocation). This behaviour probably
highlights problems in your network infrastructure or instability of
the repository manager. See [1] for more details.
Originally I switched to nexus because [2] contained all artifacts
that I needed, so I could trim my settings.xml to just two entries
(repository/pluginRepository). Since then I started to use nexus on my
local machine too, mostly to debug deployment scenarios. It barely use
any memory so I just keep it running. (disclaimer, I am affiliated
with Sonatype).

My version of m2eclipse is 0.9.5.20080717-1821. "Unfortunately" all
external repos work fine at the moment, so I cannot provide a thread
dump right now. When it happens again I will certainly post one. One
thing that might be helpful is that external artifacts which have
been put in our repo by ourself did not had an associated pom.xml,
which I have read in another thread causes a lookup in the other
repos. I remedied that and it seems that that stops most of the
annoying requests. If I get this kind of problem again I might give
nexus a try. What was your reason for switching?

Jan,
Can you please provide some thread dumps when m2e gets into such
"locked" state (see [1]) and exact version of m2e you're using?
Also, you may want to try nexus [2]. I don't think I had a single
build hang since I switched my local dev machine to nexus few months
ago.

Hi,
I have the following problem: I use Archiva 1.0, Maven 2.0.8 and
the m2eclipse plugin. All external repos are mirrored by our
Archiva repo. If one of the external repos is really slow, eclipse
hangs while building the workspace. The reason for the external
repo being slow might be that archiva is requesting one of our
locally installed artifacts from an external repo or just because
the external server is simply busy. Even if i turn our Archiva
server off the plugin or Maven still tries to get each artifact and
hangs. This makes it impossible to continue working (or at least I
have to wait a very very long time). I would like to introduce
maven in my company but this behavior would definitly cause an
outcry. I have read that Archiva 1.1.1 allows to set a timeout.
Would that solve the problem or is that the wrong track? Am I doing
anything wrong (besides turning our Archiva server off). Any help
is very much appreciated.
