While we may choose not to use the PLCTlab machines going forward it would be useful to understand if this was a one-off, or whether the dynamic parallel setup should be adjusted in this case.

Start with the linked Jenkins consoleFull log for Test_openjdk17_hs_extended.openjdk_riscv64_linux_testList_2/4 and compare it with a rerun using the provided Grinder link on test-plctlab-ubuntu2204-riscv64-2. Determine whether the 25-hour timeout is reproducible or a one-off, and document whether the dynamic parallel setup needs adjustment.
