Strange build errors 

Hi all,

I just noticed that again one of my commits failed even if I did the full build.
An investigation showed that it exited somewhere in the API module.
I have seen this occasionally and I think it might be related to concurrent builds.
Cause I get these random failures whenever we have concurrent build jobs running.

Would really like to find out the reason for this.

So if you see any failures with the build complaining about some exit code, try simply re-running the build.

Chris

Could this be related to some ulimit stuff?
(Also observed something like that in our env, I think).

    I would assume it's related to file handles, however I don't really know where to find out why the os is killing the jobs. Perhaps increasing the max open file handles will help.

    Hi Chris
    
    Thanks for the info ... i first thought it was because of my fix to odd-size arrays - but verify succeeded without any problems.
    I'm neither build nor jenkins pro ... so i can't help much - but if i see anything i'll report.
