[00:02:15] [01] [00:00:00] Building devel/llvm10 | llvm10-10.0.1_5
[09:56:37] [01] [09:54:22] Finished devel/llvm10 | llvm10-10.0.1_5: =

Still no reproduction of the build failure.

FYI:

swap/paging space use:
1271Mi MaxObsUsed

Memory use:
1938Mi MaxObs(Act+Lndry+SwapUsed), 2180Mi MaxObs(Act+Wir+Lndry+SwapUsed)

RAM Use:
712760Ki MaxObsActive, 370520Ki MaxObsWired, 961312Ki =
MaxObs(Act+Wir+Lndry)
