Ok Linus suggested I check slabinfo before and after. I ran contest for a few days till I recreated the problem and it did recur. I don't know how to interpret the information so I'll just dump it here: Looks OK. Could we see /proc/meminfo and /proc/vmstat? meminfo: MemTotal: 257296 kB MemFree: 47468 kB Buffers: 27028 kB Cached: 7480 kB SwapCached: 272 kB Active: 154968 kB Inactive: 42756 kB HighTotal: 0 kB HighFree: 0 kB LowTotal: 257296 kB LowFree: 47468 kB SwapTotal: 4194272 kB SwapFree: 4193816 kB Dirty: 1116 kB Writeback: 0 kB Mapped: 3740 kB Slab: 8564 kB Committed_AS: 6580 kB PageTables: 196 kB ReverseMaps: 1381 These numbers _look_ wrong, but ext3 truncate does funny things. Could you now run a big usemem/fillmem application to try to allocate and use 200 megs of memory, then resend /proc/meminfo? post usemem: MemTotal: 257296 kB MemFree: 86168 kB Buffers: 392 kB Cached: 2244 kB SwapCached: 632 kB Active: 159484 kB Inactive: 1380 kB HighTotal: 0 kB HighFree: 0 kB LowTotal: 257296 kB LowFree: 86168 kB SwapTotal: 4194272 kB SwapFree: 4192668 kB Dirty: 60 kB Writeback: 0 kB Mapped: 1768 kB Slab: 6748 kB Committed_AS: 6588 kB PageTables: 196 kB ReverseMaps: 619 Con | ||||||||||
