Running bonnie on a MFS filesystem will lock up my 3.1-Stable system everytime if the size is larger than the amount of RAM available. (bonnie works fine otherwise). # cd /tmp (MFS filesystem) # bonnie -s 192 (system has 128MB ram, MFS has ~465MB avail) Basically, bonnie tries hard to bench the MFS filesystem. The disk goes crazy swapping, but eventually the disk activity stops with everything else. No console messages, no response to console input (a tty), and then, after watching a stupid movie on TV, I pushed reset. Note, if I run bonnie with a -s 10 or 100, it runs fine: Machine MB K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU /sec %CPU MFS-10 10 14211 80.3 35932 71.0 28897 76.0 17938 99.9 77781 99.9 9287.2 197.4 MFS-100 100 14158 84.5 23113 44.9 18733 51.6 13724 79.9 31208 47.3 3445.8 138.2 Details: System runs 2 March 1999 RELENG_3 sources and is configured for SMP (dual PII).
