I've seen incremental compilation fail when some build steps silently fail - 
worst offender in my experience was XML validators in WTP, but that was a 
couple years ago so it might have been fixed.  I've also seen something that 
looks like this when using the Maven M2Eclipse plug-in; it seems that it 
gobbles up the status bar message and then leaves it blank while it either 
does or does not continue compiling behind the scenes, so sometimes I'll 
save a file and it'll seem that nothing is happening and then a few minutes 
later I'll see problems.  I've never seen this in a plain JDT install, I 
have only ever seen it with WTP or with Maven, but I assume that other 
builders or validators could cause similar bugs.

As Eric says, it would be good to know more about the exact symptoms.

When you say you can "see nothing obvious" in the error logs, does that mean 
that there are errors happening but they appear unrelated?
