>             Project: Mesos
>          Issue Type: Bug
>          Components: allocation, gpu
>    Affects Versions: 1.4.0
>            Reporter: Sai Teja Ranuva

> I was running a job which uses GPUs. It runs fine most of the time. 
> But occasionally I see the following message in the mesos log.
> "Collect failed: Requested 1 but only 0 available"
> Followed by executor getting killed and the tasks getting lost. This happens even before
the the job starts. A little search in the code base points me to something related to GPU
resource being the probable cause.
> There is no deterministic way that this can be reproduced. It happens occasionally.
> I have attached the slave log for the issue.
> Using 1.4.0 Mesos Master and 1.4.0 Mesos Slave.
