Not getting messages from low-volume feed

[Aleksa Jakovljevic]

HI all,

I've taken the time to adjust an available stomp-client in python for my own needs and that seems to work, but I have an issue with the VSTP feed.

When I start my client and leave it running (using wakepy), it stays connected but does not appear to get any new message from the VSTP feed after a few minutes of inactivity (I've confirmed this by checking with other sources, for ex. Phil's website, which lists when the last VSTP message was received) - my logfiles indicate I still get all of the stomp heartbeats requested, but I don't appear to get any new VSTP message. This doesn't seem to happen if I subscribe instead (or simultaneously, although that seems like a work-around which doesn't really solve whatever the root cause is) to the higher-activity feeds (TD or TRUST). Is this a known issue or something I'm doing wrong config-wise on my end?

Cheers,

Alex

Are you able to post some code that replicates the problem?  There are lots of subtle things it could be.

Hi Peter,

Here's as an attachment my last test run and the main file associated with it (the functions from td and vstp are probably unrelated as they are simple print to file with custom format functions). As I appear to have received every TD message for the hour or so this ran, but only 2 VSTP schedules (a look at Phil's website tells me I missed one at 22:49:40, just before I terminated the script), I'm quite confident it isn't a connection issue or a computer-going-to-sleep-and-shutting-off the-program issue on my side.

Thanks,

Alex
