Solaris

Hi,
I have a SUN server running solaris 9 and crash with the following error message.
Have anybody come across the panic message on a sun server?




panic[cpu0]/thread=3005ce5f480: alloccgblk: can't find blk in cyl, pos:0, i:612, fs:/ bno: 0

please post in the right forum. the "members only" forum is not for technical questions. thread moved to "sun solaris".

to topic:
this looks like an filesystem error. please boot you machine from cd/dvd or network and check your root filesystem.

And if you have contract with SUN, check if there's coredump created and uploaded it for root cause analysis of the issue.
What was done recently to the system? If you can track that, its easier for troubleshooting. perform fsck as instructed and check if the situation gets better
