IO_PENDING infinite wait on multiple sites

Reported by mqu...@gmail.com, Oct 21 2017

Issue description

UserAgent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/61.0.3163.100 Safari/537.36

Steps to reproduce the problem:
I don't have reproduction steps, but this morning I've been unable to use Chrome to browse a number of websites (but not all) from this PC, while other PCs on the same network do not exhibit the same problem in Chrome and other browsers on the same PC work as expected.

Attempting to load the web pages in question causes a hang without paint and the network requests in question are all IO_PENDING under chrome://net-internals

What is the expected behavior?
No hang

What went wrong?
See attached chrome://net-export log

Did this work before? N/A

As we don't have steps to reproduce to the problem adding appropriate labels for further triaging.

Could someone from Internals>Network team take a look into attached net log.

Thanks for the report! In both logs, there are two hanging DISK_CACHE_ENTRY events. I am not sure if that's anything of significance. I don't see anything other than that.

Is there a quicker way of finding those entries than clicking on all of them?
So...

t=71785 [st=11296]   +ENTRY_WRITE_DATA  [dt=0]
                      --> buf_len = 715
                      --> index = 1
                      --> offset = 0
                      --> truncate = true
t=71785 [st=11296]   -ENTRY_WRITE_DATA
                      --> bytes_copied = 715
t=71804 [st=11315] 

I am not sure what a timestamp entry without anything after it even means?

Was this taken from startup? If not, can you provide a net-internals log starting from a fresh Chrome session (close everything and then start logging on startup).

Hmm:
--> delegate_blocked_by = "extension uBlock Origin"

That was probably too opaque --- reporter, does it still happen with uBlock disabled?
mqudsi@, can you provide the info requested in comment #9?

Sorry for the delayed response; however unfortunately I do not have any additional information. At the time, simply restarting the browser (after killing all chrome.exe instances) did not help. After a reboot the problem was gone and I have not been able to reproduce it since.
