Hi, manangers!
Please help me... I have a Ultra60 with solaris 7.
Yesterday, When I installed 7_Recommended patch in it,
Some Problem occured. help me.

mv /user/7_Recommended.zip /tmp
cd /tmp
unzip ./7_Recommended.zip
...
...
...
When I have do 'ls', I saw /tmp/7_Recommended directory.
AND...panic occured...

Panic:a88ert: "rm->magic[0]==0xa1 && rm->magic[1]==0xa1 &&
rm->magic[2]==0xa1 && rm->magic[3]==0xa1" . ../../src/sys/mem.c:262

What is this?
Did you understand my expression.
please help me gurus.

You may have a resource problem in your tmpfs. Try unzipping under /var/tmp
instead.

>From :
Pierre Zimmermann <Pierre.Zimmermann@tecnomen.fi>
you have fulfilled your swap space = /tmp and then the system crashed.
To avoid this in future:
- set a maximum file size for /tmp in /etc/vfstab:
swap                    -               /tmp    tmpfs   -       yes
size=100m

(the "size=100m" parameter will limit the file size in your tmp filesystem)

- unzip large files only in /var/tmp or other big filesystem, check the size
of your filesystems by: df -k

Is that the actual message?  If so, then it's not one from the
Solaris kernel (we don't have a src/sys/mem.c file in Solaris proper)

If the message actually is a88ert and not assert, I have the suspicion
someone may have hacked your box and isntalled a kernel rootkit.

Hi!
Don't know it this is the case, but it might.

/tmp is a RAM-based filesystem. Amount of RAM + Swap file/slice.

If this goes full U get a big problem... Try to use a UFS filesystem
instead.

Do a "stop a" or whatever is needed to get to the ok prompt. Do "boot -b"
to bring the system up in single user with only / mounted read only. Do a
fsck of / and then "mount -o remount /" to give you root mounted
read/write. fsck your other file systems and reboot. This gets your system
back again.

Your tmp directory is problably part of swap, so you could have run into
bad memory. Try unzipping in /var/tmp instead.
