archlinux python 3.6 x64

self._socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
self._socket.connect((address, port))
self._socket.setblocking(1)
..... etc etc

all works fine
as soon as i add right at the top of the script

agent = stackimpact.start(
agent_key = '...............................',
app_name = 'abc.connect')

my app tries to send stuff before it finished receiving and so on and it all goes south.
when my app is supposed to have a serial behavior, send receive send more receive send receive.. no parallel stuff and definitely not send before it finished receiving.

is there any way to run stackimpact in an app that uses socket lib ?

    My assumption is that signals that profilers rely on interfere with blocking operations. Are you handling errors from blocking calls, such as EINTR? To test if that's the case, you can try to start the agent with disabled profilers by setting the flags cpu_profiler_disabled, allocation_profiler_disabled, block_profiler_disabled to False.
