ORA-00600: internal error code, arguments: [4194],[],[]

I have very less experience in recovery of databases. However recently i have recovered big databases and in one of the databases i saw the error-
ORA-00600: internal error code, arguments: [4194],
Doing block recovery for file 5 block 18791
Block recovery from logseq 4237, block 76 to scn 6058257035817
This was continuously coming in alert log.
After searching for a while a solution that i came across was to drop undo table space and recreate it. And this is what i did and the error got resolved.
Hope this helps
