Asankha C. Perera commented on SYNAPSE-168:
-------------------------------------------
Can you reproduce this in a Linux environment? I am not very familiar with
MacOS or have access to a system with it. Looking at the code where the NPE
occurred it seems like it could be host OS specific. Also let me know the
client HTTP version and if chunking and keepalives are used. If you are sending
thousands of requests, you may also want to tune your OS to help Synapse reach
its peak levels.

> After restarting Synapse everything backs to normal - so it isn't endpoint's
> issue.
