UFS File System Panic (4241656)

Very infrequently, while doing disk I/O, the UFS file system will panic with the error message:

panic, ufs_fault_v+0x4c:, call, real_panic_v, alloccgblk: 
can't find blk    in cyl .....

Workaround: Reboot the system and run the fsck command on the affected file system to recover from the problem.
