Ajax Spider gives error : "Channel error: cannot send/recv" and stops spidering

hi,

Recently, I have noticed that on my Jenkins instance, Ajax spidering finds about 32 URLS(sometimes 29, 30 etc) and then keeps giving errors as shown below.

The channel errors appear 1000s of times.

I am using ZAP weekly docker container image(also tried Stable version with same error) on a Jenkins machine.

Thanks,

Hi.

That's output from Firefox, that's normal according to:

After restarting the machine, it started working without any issues.
