# 事故记录: 2026-10-09 10:11:13 内核 panic (B8 加压步, 累计 4600M 不可压缩 ballast)
# panicString: userspace watchdog timeout: jailbreakd BSOD handler failed: (ipc/send) timed out
#          no successful checkins from com.apple.mediaserverd in 180 seconds
# panic 时 memoryStatus: memoryPressure=true, free=2867, fileBacked=16007, wired=33688,
#   active=14532, inactive=13224, compressorSize=291717 页(4.45GiB), compressions=578217
# 根因: 随机 ballast 被 XNU 1:1 存入压缩器(净收益0), 压缩器占满 RAM,
#   用户态守护进程被饿死 -> watchdog 180s -> panic -> 重启丢越狱
# 教训: 极限加压必须用部分可压缩 ballast(-P 50) 且控制总量, 保持 free>=2000
