We have recently upgraded to Sybase 11.9.2 with EBF8624 (Server), EBF 8550 (Open
Client) and EBF 7696 (Open Client) on Win NT4 SP5. Recently we have increasing
the crashes on the backup server. It seems that it is mostly carshing during the
automatic scheduled dump (DB or Transaciton log dump). Any ideas?

I can find the following messages in the NT Event Log:
"The description for Event ID ( 12 ) in Source ( SYBPERF ) could not be found.
It contains the following insertion string(s): 7, [SQLBOX1194] - NT Performance
Monitor has started monitoring SQL Server.."

Followed by:
"The description for Event ID ( 4097 ) in Source ( DrWatson ) could not be
found. It contains the following insertion string(s): , 8, 14, 2000, 17, 0,
3, 327, 80000001, 1001570a, <nosymbols>."

Here the messages in the Sybase Error Log:
