Bala Kolla commented on JENA-703:
---------------------------------

Can you help me experiment with this approach? I would like to see if this 
could help us resolve the issue (saturating the system resources, CPU etc..) 
mentioned in JENA 801.

> TDB - Ensure readers don't block writeback forever.

>             Project: Apache Jena
>          Issue Type: Improvement
>          Components: TDB
>    Affects Versions: Jena 2.11.1
>            Reporter: Andy Seaborne
>
> The commit queue can only be flushed when the main storage is quiet.  A 
> stream of readers can lead to the main storage never being quiet.
> One possibility is to place a maximum (quite high) on the number of readers 
> allowed after the decision to flush the journal to main storage. If exceeded, 
>  then lock readers for a while, flush and resume.
