1404357 - Local builds sometimes fail due to random network errors (in sccache?)

Status: NEW

(Firefox Build System :: General, defect)

I sometimes get random local build failures because of network errors. That really shouldn't happen. I'm fairly sure this is from sccache because it only started happening after I enabled sccache. But the output isn't really helpful so it might be something else.

Sample run:

kats@kgupta-air mozilla-w2$ mach build binaries
 0:01.08 /usr/bin/make -C /Users/kats/zspace/mozilla-w2/obj-host-opt -j4 -s backend
 0:03.60 /usr/bin/make -j4 -s binaries
 0:10.81 Elapsed: 6.65s; From dist/include: Kept 5428 existing; Added/updated 0; Removed 0 files and 0 directories.
 0:11.97 force-cargo-library-build
 0:24.88 error: Connection to server timed out
 0:24.88 make[2]: *** [Unified_cpp_gfx_layers11.o] Error 2
 0:24.88 make[1]: *** [gfx/layers/target] Error 2

Also this is intermittent in that if I run the same build command again immediately after it will usually work fine.

Servo is seeing the same symptoms since enabling sccache on our CI build machines.
