2590845 - ASE timeslice error , function in the stack __xstat64() - SAP ASE

• A timeslice message in the SAP ASE errorlog can be seen with __xstat64 in the message.

timeslice -1761, current process infected at 0x7ffff581b0a5 (__xstat64+0x15) 
.....
timeslice error: spid <NN> exhausted its 'time slice' of 100 milliseconds and additional 'cpu grace time' of 1500 ticks (150000 milliseconds). It has been marked for termination.

• Complete portion of timeslice error and stack might look like as below,
