Dbcc checkcatalog error 2513

Hi,

I have the following error in a server log with Sybase installed:

03:00000:00016:2009/05/16 00:55:20.49 kernel SQL causing error : dbcc checkcatalog

03:00000:00016:2009/05/16 00:55:20.49 kernel lasterror = 2513 preverror = 0 transtate = 1

I found that this error occurs when dbcc checkcatalog finds that an object exists in one system table but not in another system table where Adaptive Server expected to find it.

I tried to run dbcc checkcatalog directly to get more information but I got the following error:

1> dbcc checkcatalog(my_db)
2> go
The SQL Server is terminating this process.
1> dbcc checkcatalog(my_db)
2> go
CT-LIBRARY error:
ct_send(): network packet layer: internal Client Library error: State error: trying to write when connection is expecting a read.
CT-LIBRARY error:
ct_cancel(): network packet layer: internal net library error: Net-Library operation terminated due to disconnect


And in the same log as the first one, I found the following:

Does someone have a hint why it can be happening? Hope you can help me.

Thanks in advance.
