Hi Srikanth,
The Error was
"[ASE Error SQL1105]Can't allocate space for object 'syslogs' in database 'ECD' because 'logsegment' segment is full/has no free extents. If you ran out of space in syslogs, dump the transaction log. Otherwise, use ALTER DATABASE to increase the size of the segmen"
Since you have shutdown the Sybase , it will do crash recovery and as the sysbase is not able to recover since logsegment is getting full. so you need to expand the transaction log segment.
Follow the below sapnotes
1802842 - SYB: Error 1105 and Error 3475 in ASE error log
1810223 - SYB: Recovery of a database fails with error 3475
