I can't reproduce exactly the same problem on FreeBSD TP51.local 6.1-RC FreeBSD 6.1-RC #1: Sun Apr 9 20:07:42 CEST 2006 but I get a different problem with truss and Firefox. If I run truss -f firefox it seems to get stuck after a while. 1274: mmap(0x0,36864,(0x3)PROT_READ|PROT_WRITE,(0x1002)MAP_ANON|MAP_PRIVATE,-1,0x0) = 689876992 (0 1274: kse_release(0x8064fa0) = 0 (0x0) 1274: kse_release(0x8064fa0) = 0 (0x0) 1274: kse_release(0x8064fac) = 0 (0x0) 1274: kse_release(0x8064fa0) = 383 (0x17f) 1274: kse_release(0x8064fa0) = 383 (0x17f) 1274: kse_release(0x8064fa0) = 0 (0x0) 1274: kse_release(0x8064fa0) = 383 (0x17f) 1274: kse_release(0x8064fa0) = 383 (0x17f) 1274: kse_release(0x8064fa0) = 0 (0x0) ^C 1259: wait4(0xffffffff,0xbfbfe9d8,0x2,0x0) ERR#4 'Interrupted system call' 1266: wait4(0xffffffff,0xbfbfe728,0x2,0x0) ERR#4 'Interrupted system call' 1274: kse_release(0x8064fa0) = 383 (0x17f) truss firefox seems to work. If I attach truss to a running Firefox I get: [EMAIL PROTECTED] ~ $truss -f -p 1440 1440: (null)() = 0 (0x0) 1440: kse_release(0x8064fa0) = 0 (0x0) 1440: kse_release(0x8064fa0) = 0 (0x0) 1440: kse_release(0x8064fa0) = 0 (0x0) 1440: kse_release(0x8064fa0) = 0 (0x0) 1440: kse_release(0x8064fac) = 0 (0x0) 1440: kse_release(0x8064fa0) = 0 (0x0) 1440: kse_release(0x8064fa0) = 0 (0x0) 1440: kse_release(0x8064fa0) = 0 (0x0) truss: Cannot malloc -67210816 bytes for pollfd array: Cannot allocate memory Fabian -- http://www.fabiankeil.de/
