Labrad node sometimes freezes?

[egdeist]

I have an issue every once in a while where the labrad node that I use to start and stop a lot of servers sometimes "freezes." When it's frozen I am not able to start and stop servers with cxn.node.start('server') from a client connection. I can typically unfreeze it with ctrl+c in the command prompt where I started the node and then it sort of catches up. Any idea what could be going on here? Or is there some sort of error check thing I should be doing so the node can tell me what's wrong when it freezes? Thanks much!

I've never seen this and don't have enough info to reproduce it, so not sure what to tell you. It seems particularly strange that 'Ctrl-C' would fix anything; do these freezes happen when you try to run a server or just at random times? Is it possible that one of the server processes you're trying to launch is blocking waiting for user input? I don't think that should affect the node itself (the server just wouldn't connect to labrad) but that's the only thing I can think of. What OS are you using and what versions of pylabrad, labrad, python, twisted, etc. do you have?

The control-C thing is probably killing the node process and then having it
auto-restart. If you are using the windows batch file that starts the
node, it does so in an infinite loop. ctrl-c kills the python process but
not the script.

@ejeffrey, which windows batch file are you referring to?
