I recently (< a week ago) installed all the "recommended" patches for
a Solaris 2.4 system and since then the system has been crashing
regularly with a "panic: free: freeing free block" message.
I searched the readme's on all the Sun patches I could find but
couldn't find a patch for Solaris 2.4 that mentioned this message. It
IS mentioned in patches for other versions of the OS, but not for
SunOS.
Anyone have an idea of a way to fix it? Should I just start backing
out all the patches I just installed until it starts working again?
The particular file system involved is a Solstice DiskSuite
meta-device, but I don't think that is the problem: it was working
fine before the patches and I didn't install any DiskSuite patches.
The only other unusual thing in syslog is messages that say:
WARNING: md: logging device: /dev/md/dsk/d11 changed state to Hard Error
WARNING: md: logging device: /dev/md/dsk/d11 changed state to Okay
These show up after as the system reboots but I suspect they don't
indicate a real (hardware) problem, but I could be wrong. There are
no other errors or unusual messages anywhere that I can find.
BTW, this is a Sun Sparc 5 system.
Thanks,
Jim
