Hi all, I am installing a zone onto two different V445s running S10U4 and the zones are taking hours to install (about 1000 packages), that is, the problem is identical on both systems. A bit of trussing and dtracing has shown that the pkginstalls being run by the zoneadm install are making door_call calls to nscd that are taking very long, so far observed to be 5 to 40 seconds, but always in

I''ve recently upgraded my x4500 to Nevada build 97, and am having problems with the iscsi target. Background: this box is used to serve NFS underlying a VMware ESX environment (zfs filesystem-type datasets) and presents iSCSI targets (zfs zvol datasets) for a Windows host and to act as zoneroots for Solaris 10 hosts. For optimal random-read performance, I''ve configured a single

Just to let people know what my big picture is, I''m trying to write a script that will let me run a program, and name a progeny of that program that I want to debug. My script should find the first occurrence of that progeny, and run it until it finishes initializing the runtime linker, but stop it before it runs any shared library startup routines. (Failing that, I''d be okay

Hi, I have just recovered from a ZFS crash. During the antagonizing time this took, I was surprised to learn how undocumented the tools and options for ZFS recovery we''re. I managed to recover thanks to some great forum posts from Victor Latushkin, however without his posts I would still be crying at night... I think the worst example is the zdb man page, which all it does is to ask you

Hi all, I just had a panic with dovecot 1.1.6, two days after replacing 1.0.15 with it in production. Here are the logs immediately preceding the panic, I think they're related. It seems the user connected simultaneously from two different clients, from his own computer and a webmail running on the server, then manipulated mail folders on one side, and logged out. The panic occurred 3

This happened whether I built with gcc3, gcc4, or SunStudio 12. Using pstack I found that the code was crashing in avl_create(). Using truss I found that identically named functions in the Solaris /lib/libavl.so.1 library were being used instead of the AVL functions provided in avl.c in the foreign package. To verify, I replaced all of the "avl_" and "AVL...
