Hi, When putting some quite significant stress on the system (namely by forwarding about a thousand mails at once through exim, triggering spamassassin and clamav scans and stuff), also including swapping and loads of processes fighting over the CPUs, I start getting the following output on my serial console. The box seems unresponsive for a while, but does come back once the load/swapping lessens. This is a dual opteron on a Tyan S2882 mainboard, 1GB memory, ultra320 scsi disk on the onboard adaptec controller plus a pair of SATA drives in gmirror (raid-1) on the onboard SiI controller. Swap is on the SCSI drive. Could this be related to the panic I saw in my earlier messages (5.4- panic)? /Eirik KDB: stack backtrace: getdirtybuf() at getdirtybuf+0x1bb flush_deplist() at flush_deplist+0x57 flush_inodedep_deps() at flush_inodedep_deps+0x89 softdep_sync_metadata() at softdep_sync_metadata+0x66 ffs_fsync() at ffs_fsync+0x315 fsync() at fsync+0x158 syscall() at syscall+0x233 Xfast_syscall() at Xfast_syscall+0xa8 --- syscall (95, FreeBSD ELF64, fsync), rip = 0x801490100, rsp = 0x7fffffffae08, rbp = 0x5f17b8 --- KDB: stack backtrace: getdirtybuf() at getdirtybuf+0x1bb flush_deplist() at flush_deplist+0x57 flush_inodedep_deps() at flush_inodedep_deps+0x89 softdep_sync_metadata() at softdep_sync_metadata+0x66 ffs_fsync() at ffs_fsync+0x315 fsync() at fsync+0x158 syscall() at syscall+0x233 Xfast_syscall() at Xfast_syscall+0xa8 --- syscall (95, FreeBSD ELF64, fsync), rip = 0x80079c100, rsp = 0x7fffffffe7b8, rbp = 0x50f070 --- KDB: stack backtrace: getdirtybuf() at getdirtybuf+0x1bb flush_deplist() at flush_deplist+0x57 flush_inodedep_deps() at flush_inodedep_deps+0x89 softdep_sync_metadata() at softdep_sync_metadata+0x66 ffs_fsync() at ffs_fsync+0x315 fsync() at fsync+0x158 syscall() at syscall+0x233 Xfast_syscall() at Xfast_syscall+0xa8 --- syscall (95, FreeBSD ELF64, fsync), rip = 0x801490100, rsp = 0x7fffffffae08, rbp = 0x5f17b8 --- Limiting closed port RST response from 472 to 200 packets/sec KDB: stack backtrace: getdirtybuf() at getdirtybuf+0x1bb flush_deplist() at flush_deplist+0x57 flush_inodedep_deps() at flush_inodedep_deps+0x89 softdep_sync_metadata() at softdep_sync_metadata+0x66 ffs_fsync() at ffs_fsync+0x315 fsync() at fsync+0x158 syscall() at syscall+0x233 Xfast_syscall() at Xfast_syscall+0xa8 --- syscall (95, FreeBSD ELF64, fsync), rip = 0x801490100, rsp = 0x7fffffffd918, rbp = 0x5eb310 ---
