Frequent lockups with SMP and heavy NFS access
I've been experiencing a lot of lockups (system completely dead, no reaction at the keyboard, can't ping) on an Intel SMP machine running CURRENT. Normally I do my kernel builds over NFS, but in the last few months I haven't been able to complete a 'make world'. Along with -DNOCLEAN I can get a build done in about 4 attempts; local builds work fine. NFS builds also work fine with other single processor machines. Questions: 1. Has anybody else seen this? 2. How should I approach looking for the problem?

How should I approach looking for the problem? I've seen intermittent lockups where everything is dead, but I can break into DDB via serial console. They may be NFS-related, as it often crashes a half-hour before I get in to work, which could be due to co-workers trying to bulid from my NFS-exported ports tree. ps inside DDB doesn't show anything obviously wrong to my untrained eyes. Well, then at least you can get a dump and others can look. In my case, the machine is completely catatonic.
