I have a project with ~70k targets including generated header and source files that builds fine without concurrency (-j1):

 

...found 72133 targets...

...updating 5981 targets...

<snip>

...updated 6237 targets...

 

but stops in the middle of the build when using concurrency (-j2 to –j8). There are no failures reported, it just stops and reports the target count that was updated but does not build all targets:

 

...found 72133 targets...

...updating 5981 targets...

<snip>

...updated 5930 targets...

 

If I run it again a number of times w/ concurrency enabled it will eventually complete (not sure why target count increased):

 

...found 78019 targets...

...updating 2094 targets...

<snip>

...updated 1778 targets...

 

...found 78019 targets...

...updating 2088 targets...

<snip>

...updated 1772 targets...

 

...found 78019 targets...

...updating 316 targets...

<snip>

...updated 316 targets...

 

Any ideas on how to debug this issue?

 

I am using SVN 77778 but have seen the issue since 4-11-2011 (not sure what SVN version at that time).

 

Thanks,

 

Chris
