I cced this mail to bugzilla (hoping this is correct, if not let me know). This is the cpu from /proc/cpuinfo: CJ7:~# cat /proc/cpuinfo Processor : XScale-IXP42x Family rev 1 (v5l) BogoMIPS : 266.24 Features : swp half fastmult edsp CPU implementer : 0x69 CPU architecture: 5TE CPU variant : 0x0 CPU part : 0x41f CPU revision : 1 Cache type : undefined 5 Cache clean : undefined 5 Cache lockdown : undefined 5 Cache format : Harvard I size : 32768 I assoc : 32 I line length : 32 I sets : 32 D size : 32768 D assoc : 32 D line length : 32 D sets : 32 Hardware : Linksys NSLU2 Revision : 0000 Serial : 0000000000000000 and this is /proc/meminfo: CJ7:~# cat /proc/meminfo MemTotal: 29988 kB MemFree: 2164 kB Buffers: 392 kB Cached: 8008 kB SwapCached: 5204 kB Active: 11808 kB Inactive: 6884 kB HighTotal: 0 kB HighFree: 0 kB LowTotal: 29988 kB LowFree: 2164 kB SwapTotal: 497972 kB SwapFree: 471008 kB Dirty: 180 kB Writeback: 0 kB AnonPages: 10084 kB Mapped: 5896 kB Slab: 3692 kB PageTables: 1008 kB NFS_Unstable: 0 kB Bounce: 0 kB CommitLimit: 512964 kB Committed_AS: 135880 kB VmallocTotal: 991232 kB VmallocUsed: 17104 kB VmallocChunk: 966652 kB As you see it has about 32Mb ram + 500mb swap. At the moment there are some daemons running, like ssh, apache, mysql, and heartbeat v1 and virtual memory is moderately empty. No particular task is done, just a "white running" with services up with default configurations (i have yet to configure them). A typical "top" header is here: top - 08:29:12 up 8 min, 1 user, load average: 0.05, 0.54, 0.39 Tasks: 81 total, 1 running, 80 sleeping, 0 stopped, 0 zombie Cpu(s): 1.0%us, 1.0%sy, 0.0%ni, 98.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 29988k total, 28880k used, 1108k free, 548k buffers Swap: 497972k total, 27256k used, 470716k free, 8516k cached I found something interesting in /var/log/messages: i copy a little of it here because i found something strange. After starting heartbeat-2 there are kernel messages complaining on memory. There are no log like that when i started heartbeat v1. By converse, this happens every time i started heartbeat-2. Yesterday i tried several times and every time there are kernel messages like that: May 21 16:13:14 CJ7 heartbeat: [5025]: WARN: Core dumps could be lost if multiple dumps occur May 21 16:13:14 CJ7 heartbeat: [5025]: WARN: Consider setting /proc/sys/kernel/core_uses_pid (or equivalent) to 1 for maximum supportability May 21 16:13:14 CJ7 heartbeat: [5025]: WARN: Deprecated 'legacy' auto_failback option selected.
