April 22, 2004 - Cache' processes incorrectly removed on Windows
InterSystems has corrected a defect that can cause Cache' processes to be incorrectly deleted from Cache'. This defect is present on Windows platforms only and applies to currently released Cache' 5.0.x versions.
Only processes that call out of Cache' using $ZF() and modify their Windows security profile are at risk of encountering this defect. The likelihood of encountering this problem is low but the effects could be severe including causing Cache' to hang. To determine if your system has encountered this defect check the cconsole.log file for a message indicating that a dead process has been "cleaned":
04/20-17:28:33:734 ( 4184) cleaned dead job, pid: 4224
If the PID that has been cleaned still exists as a Windows process then the problem may have occurred. Please note that the "cleaned" message is evidence that normal Cach� functionality has been triggered to protect against dead processes, it is not, by itself, evidence of the defect. Also, please remember that PIDs are quickly reused in a running Windows system so unless you find the PID in existence at the Windows level very shortly after the timestamp on the "cleaned" message you have likely not encountered the defect.
The correction for the defect is referenced as JO1799 and can be delivered in an adhoc build.
If you have any questions regarding this, please contact the InterSystems Worldwide Response Center at [EMAIL PROTECTED]
