Issue/Introduction

VM:Operator ABENDs with DIE000

 

 

 

Environment

Release : 3.1   VM:Operator

Cause

If two or more VM:Operator macros execute the TCP/IP utility commands PING or TRACERTE at the same time, it is possible to see the DIE000 ABEND. 

Resolution

While DIE000 is a generic ABEND, we have encountered a repeatable failure for a specific reason. If two or more VM:Operator macros execute the TCP/IP utility commands PING or TRACERTE at the same time, it is possible to see the DIE000 ABEND. IBM confirmed that these TCP/IP commands are not thread safe (i.e. CMS multitasking compliant) and will have issues if executing simultaneously.

 

Symptomatically, the message "DTCPIN0039E Unable to setup external interrupt handler" has been seen when the DIE000 ABEND has occurred. If the PING or TRACERTE commands target an unresponsive IP address this greatly increases the likelihood that an ABEND will occur.

 

 

Additional Information

If you are experiencing this, we encourage you to engage IBM to enhance/fix the TCP/IP utility commands.
