Mike Lerch commented on THRIFT-347:
-----------------------------------
Same issue here as Nathan Marz. Everything was working great until I tried to
retrieve a larger bit of data (about 5kb). Before applying the patch, the
request would fail with the 'TSocket: timed out reading 4 bytes from' message.
After the patch, the script hangs indefinitely using 100% CPU.
Tried TBuffered, TFramed, and standard TSocket connections, all with the same
result.
Does not happen with other client libraries, only PHP, which tells me it isn't
the server itself.
Any advice?

> ==================================
> I have a patch that fixes the problem that I'll attach. It looks like
> fetchAll() doesn't know the difference between a timeout and a blocking port.
