GRC error - GThread-ERROR

GRC was working great for me two days ago. Shut the computer down
with everything working. Today I started it up (haven’t changed a
thing) and now I’m getting this error when trying to execute
flowgraphs:

GThread-ERROR **: file
/build/buildd/glib2.0-2.30.0/./gthread/gthread-posix.c: line 348
(g_thread_create_posix_impl): error ‘Invalid argument’ during
‘pthread_attr_setschedparam (&attr, &sched)’

Another flowgraph that will execute runs very choppily and poorly,
eventually locking up completely. All was well last time I had it
running.

Could anyone tell me what might be causing these issues and why it
seemed to start out of thin air?

Thanks,

Andy

If you’re talking about the Ubuntu Update Manager, then no. I get
notified of software updates but it doesn’t download or install them
unless I tell it to, which I haven’t.

Andy,
Are you still having this problem? It seems way low-level, so it’s
hard to determine what might have gone wrong in GNU Radio.

I know you said you didn’t have automatic updates turned on, but
perhaps you updated recently in a way that required a computer restart
that you hadn’t done immediately? A change to glib2.0 might request
that.

This might seem like an extreme measure, but it’s the only one I can
think of based on your email. Can you just rebuild GNU Radio from
source and reinstall it?
