Symptom

  • Reporting multiple timeslices and kernel engine messages, e.g.

timeslice -1001, current process infected at 0xe5bfdf (ptn_unkeep+0x6f)

  • The timer errors, where ASE isn't able to clear the negative values look like this:

kernel  Warning: The internal timer is operational and has recovered from previous failure.
kernel  Warning: The internal timer is not progressing. If this message is generated multiple times, report  to Sybase Technical Support and restart the server (alarminterval=-739). 

  • These are also variations of the same problem:

kernel timeslice -1001, current process infected at 0x150a8b4 (atomic_try+0x2)
