I think that the same than #36084. The test seems to be stuck in a usleep called by svmon as shown by the samples taken.

184: 0x10002f304 (runtime.usleep:509) 0x10003fe33 (runtime.sysmon:4333) 0x1000373e3 (runtime.mstart1:1238) 0x1000372cb (runtime.mstart:1203)

It's not just the builder as I was able to get the same failure on my local machine.
Is it possible that a deadlock occurs between sysmon and pprof functions ?
