Hi. I tried to install CA Wily Introscope 8.1, an enterprise application performance monitoring framework, on FreeBSD. It is Java-based and works, if installed. Unfortunately, the installer panics my machine reproducably when it exits after the installation: panic: Lock (rw) Name Cache exclusively locked @ /usr/src/sys/kern/vfs_cache.c:589 I'm using -CURRENT r196074 (i386) at the moment. Kernel config: http://sites.google.com/site/lwfreebsd/Home/files/kernelconfig-CURRENT.txt?attredirects=0 I have a kernel dump for further analysis (the installation archive may not be published, I suppose): $ kgdb ... vmcore.12 (kgdb) bt #0 doadump () at pcpu.h:246 #1 0xc063cd1e in boot (howto=260) at /usr/src/sys/kern/kern_shutdown.c:419 #2 0xc063cff2 in panic (fmt=Variable "fmt" is not available. ) at /usr/src/sys/kern/kern_shutdown.c:575 #3 0xc067e515 in witness_assert (lock=0xc0b160fc, flags=Variable "flags" is not available. ) at /usr/src/sys/kern/subr_witness.c:2235 #4 0xc063a1d5 in _rw_assert (rw=0xc0b160fc, what=Variable "what" is not available. ) at /usr/src/sys/kern/kern_rwlock.c:1020 #5 0xc063a80b in _rw_runlock (rw=0xc0b160fc, file=0xc0905c58 "/usr/src/sys/kern/vfs_cache.c", line=589) at /usr/src/sys/kern/kern_rwlock.c:526 #6 0xc06b8297 in cache_lookup (dvp=0xc733c218, vpp=0xf63fcc70, cnp=0xf63fcc00) at /usr/src/sys/kern/vfs_cache.c:589 #7 0xc06b837d in vfs_cache_lookup (ap=0xf63fcc48) at /usr/src/sys/kern/vfs_cache.c:881 #8 0xc08a79c2 in VOP_LOOKUP_APV (vop=0xc65ec880, a=0xf63fcc48) at vnode_if.c:123 #9 0xc0de7547 in linux_getcwd (td=0xc718e240, args=0xf63fccf8) at vnode_if.h:54 #10 0xc0898567 in syscall (frame=0xf63fcd38) at /usr/src/sys/i386/i386/trap.c:1073 #11 0xc087b8c0 in Xint0x80_syscall () at /usr/src/sys/i386/i386/exception.s:261 #12 0x00000033 in ?? () Previous frame inner to this frame (corrupt stack?) Panicing the kernel with getcwd() is strange. :-D Lucius
