在ASE12.53 的bug list 中能够看到你的这个报错，
bug ID : 417301
The message "timeslice < negative number > , current process infected" maybe reported in the errorlog together with a stack trace which includes the modules 'ns_handle' and 'ns_prep_stmnt' if a batch including together a CREATE TABLE statement and a SELECT executing java was being executed and an error condition happened.  
虽然你的是1254，但不排除也会有这个bug 哦。

所以，我同意2楼的说法，你可以试着先打补丁再做观察。

the default "cpu grace time" of 500 is generally acknowledged as being too low, and it is common to have to increase this value to 2000. There have been some timeslice CRs where the workaround was to increase cpu grace time by this amount. You can increase it by :

sp_configure 'cpu grace time', 2000

There are no negative effects from having a high CPU grace time

Also, the version of ASE is over 4 years old and End Of Life. So for the short term, you should apply ASE 12.5.4 ESD10 to make sure you are running with the most recent 12.5.x version possible.
