Something is holding on to one of the taskqueues blocking the request 
processesing. I'm not sure what caused it but backstepping ATA doesn't 
make things work at least, suggesting to look somewhere else...

For me at least network seems to be troublesome, if I exclude as much 
network related code as possible in the config, I can resume just fine.

YMMV as usual...
