No Buffer Space Available Linux
7 participants alexwlchan commented May 28, 2015 Spotted during scalability testing. Felix falls over three times within the course of a second, and then seems to recover (no more logs are dropped after this). Felix seems to continue running (or at least upstart brings it back). I was attempting to spin up 1000 no buffer space available mac endpoints on the same host as part of the scalability testing. Memory consumption then goes to ~300MiB and sits there. No obvious other errors in the logs or in the test output. 2015-05-28 10:02:11,225 [ERROR][15031/1] calico.felix.actor 227: Exception processing 8c91a0d16cb9 (watch_interfaces) Traceback (most recent call last): File "/usr/lib/python2.7/dist-packages/calico/felix/actor.py", line 225, in _step result = msg.method() File "/usr/lib/python2.7/dist-packages/calico/felix/devices.py", line 257, in watch_interfaces data = s.recv(65535) File "/usr/lib/python2.7/dist-packages/gevent/socket.py", line 385, in recv return sock.recv(*args) error: [Errno 105] No buffer space available 2015-05-28 10:02:11,227 [ERROR][15031/2] calico.felix.felix 152: Greenlet failed:

Join them; it only takes a minute: Sign up Python loop causing “error: [Errno 105] No buffer space available” up vote 0 https://github.com/projectcalico/felix/issues/595 down vote favorite I have a loop that goes through a Range(300) and creates a Thread with 'import threading'.. So this creates 300 threads, which is correct. However I'm getting a problem where not all the threads start up, and a error is shown in console. as below File "/usr/local/lib/python2.7/dist-packages/scapy/supersocket.py", line 29, in send return self.outs.send(sx) error: [Errno 105] No buffer space available Q: Is there a way I http://stackoverflow.com/questions/31746401/python-loop-causing-error-errno-105-no-buffer-space-available can increase the buffer? Q: Is this a python limit, or a process limit? python multithreading share|improve this question asked Jul 31 '15 at 12:37 Dusty Boshoff 310417 2 Do you really need 300 threads or just want to execute 300 (function, arguments) pairs using multiple threads? If so, try concurrent.futures. –Bartosz Marcinkowski Jul 31 '15 at 12:41 This might be helpful: stackoverflow.com/questions/481970/how-many-threads-is-too-many –IanAuld Jul 31 '15 at 12:42 I use scapy to do a sendp (send packet function)300 threads, and I would like all ~300 iterations to be started at the same time. I have never used concurrent.futures –Dusty Boshoff Jul 31 '15 at 12:45 concurrent.futures is working for me. Thanks @BartoszMarcinkowski –Dusty Boshoff Jul 31 '15 at 13:18 add a comment| 2 Answers 2 active oldest votes up vote 1 down vote An easy way to limit the amount of concurrent threads is to use concurrent.futures.ThreadPoolExecutor. Create an instance with the maximum number of threads as argument: from concurrent.futures import ThreadPoolExecutor executor = ThreadPoolExecutor(100) for i in range(300): executor.submit(do_something, i) share|improve this answer answered Aug 11 '15 at 12:53 BlackJack 2,2931714 add a comment| Did you find this question interesting?
