Hello,
I’m not sure if this is the right place for this, but I am kindly
requesting
help with the http push module. It seems to sporadically not send
responses
to long polling JavaScript clients. In the wild, I have clients who
start
the long poll, but then never receive messages from the publisher no
matter
how many POSTs are sent. Aborting the XMLHttpRequest and then
re-establishing the long poll seems to work.
In my error logs, I can find this:
2010/05/20 23:49:33 [error] 5593#0: push module: worker 5593 intercepted
a
message intended for another worker process (913) that probably died
Which I assume may be the problem; perhaps the worker died and then
never
closed the connection? I could not reproduce this problem in a
controlled
environment, but exhausting the number of workers available in the
worker_connections directive caused the symptoms to re-appear: long
polling
clients do not receive messages until they re-establish the long poll.
Here is my relevant information; any help would be appreciated. Thanks
in
advance!
