Hi,
I already sent this message and never get any feedback. Here is my
problem.
I have hearbeat 2.1.3 (Same problem with 2.1.2).
I am using a Master/Slave model.
I am using the communication link of heartbeat to transfer data from 2 nodes.
Data is state and data. Since, with Ethernet, I am limited in size, I am
transferring multiple chunks of 8K data for up to 1MB (120 * 8KB approx).
The problem is after couple of data set (maybe 300, 400, sometime more,
sometime less... but always), the function send_ordered_nodemsg hang and I am
not able to transfer data anymore. It looks, from debug information that it
hangs in function socket_resume_io_read.
I have tried Unicast and Broadcast.
>From Dejan, it maybe that I am pushing heartbeat communication layer to the
>limit. I am a little bit surprise that 1MB of data can be a problem.
I am stuck now and I need a solution cause my application is not usable and I
may have to look at other ha package (I really don't want to).
Any input, suggestions, whatever will be greatly appreciated.
May it be good to consider creating a new communication link (client/server).

Objet : Problem with function send_ordered_nodemsg
Hi,
I currently have a problem with my software that hangs when I call the
function send_ordered_nodemsg (exhibit the same problem with sendnodemsg). I
am able to send many message (many dozens) and then, it hangs. With extra
debug, I found that it hangs somewhere in the function socket_resume_io_read. I
base my code on the CIB implementation.
I am requesting any helps that may help me find the problem. I know that CIB
is using this function so I think the problem is on my side or I don't know
exactly how to use it but I am trying to find this problem since many days now.
Maybe somebody have some experience with his function and hit the same problem
before.
Any help will be more than appreciated.
