      Description

      Hi,All
      I'am using the storm's multilang throughing PHP. But it seems have some problem.
      Then my spout is a php script which read contents from a file.And in the beginning of the 4Mb content,which runs correctly.But the php process will blocks in the write(1,xxxx...,when i strace -p the php spout.
      But when i use 'cat' read from the /proc/pid/fd/1 which is the php process STDOUT. All of the content had been handle correctly in the bolt is still there.
      So, i doubt that spout hangs out when write(1,xxx , is because that the process's STDOUT buffer is full of contents. But how can i prevent this issue.
      My environment is
      Linux : 2.6.32_1-9-3-1 kernel.
      Java: 1.6.0_33
      Storm:0.8.2 or 0.8.1
      PHP: 5.2

      Thx
      Sean
