It's not really strange nor random. dcache has settings for: dcache.net.wan.port.min = 20000 dcache.net.wan.port.max = 25000 dcache.net.lan.port.min = 20000 dcache.net.lan.port.max = 25000 (valued copied from one of my testpools) when .wan. is for wan-safe protocols and xrootd being unsafe is .lan. If the pool has max-min less than the amount of movers allowed, the pool will run out (and it will give a nice error message). If will eventually recover when the other transfers end and ports are freed.
