fetch: Log bgfetch_no_thread #4080

Closed AlveElde closed 6 months ago

AlveElde commented 6 months ago

The log emitted for a bgfetch task when there are no available threads in the thread pools currently looks like this:

1004 Begin           b bereq 1003 bgfetch
1004 VCL_use         b vcl1
1004 BereqAcct       b 0 0 0 0 0 0
1004 End             b

This PR makes it easier to understand what happened:

1004 Begin           b bereq 1003 bgfetch
1004 VCL_use         b vcl1
1004 FetchError      b No thread available for bgfetch
1004 BereqAcct       b 0 0 0 0 0 0
1004 End             b
