Forcibly detaching task taskname TCB address TCBaddress.
While the agent was shutting down, the VNAC dispatcher detected that one or more tasks had not ended. The VNAC dispatcher is attempting to forcibly stop the named task taskname with the TCB at address TCBaddress.
Destination: VNCOUT, VNCLOG, and GUI console.
Action: None.
Shutdown proceeding…
While the agent was shutting down, the VNAC dispatcher detected that one or more tasks had not ended. The VNAC dispatcher is attempting to forcibly stop the tasks. This message is issued every ten seconds until the main VNAC task determines the agent is not shuttng down, at which point it will terminate the dispatcher and end. This may result in a system A03 abend.
Destination: VNCOUT, VNCLOG, and GUI console.
Action: None.
lda-field total-bytes Mbytes
When VNAC recognizes a Short On Storage condition, message VNC0341W is issued to show the percent of available storage in use. Message VNC0345I accompanies VNC0341W to show the current storage in use and limit values from the system LDA block.
lda-field is the name of the LDA field whose value is shown:
| LDALIMIT | Below 16M V=V Region limit value |
| LDAELIM | Above 16M V=V Region limit value |
| LDALOAL | Below 16M USER Region alloc value |
| LDAHIAL | Below 16M AUTH Region alloc value |
| LDAELOAL | Above 16M USER Region alloc value |
| LDAEHIAL | Above 16M AUTH Region alloc value |
total-bytes is the total value of the field shown, in bytes.
Mbytes is the value of the field in Megabytes.
Action: None.
VNAC is canceling Strobe due to SOS condition
VNAC has recognized a storage shortage condition while a Strobe test is running. Strobe requires a good deal of virtual storage. To prevent Strobe from interfering with production work, VNAC has canceled the Strobe test.
Action: Increase the REGION size for the VNAC agent or try running Strobe with a shorter time interval.
VNAC is taking a system dump due to SOS condition
The VNAC agent has detected that storage use below the 16-megabyte line has exceeded 75% or storage use above the 16-megabyte line has exceeded 90% and the SOSSDUMP global configuration parameter specified (or defaulted) to Yes. The VNAC agent performs a system dump that can be forwarded to SDS to aid in problem determination.
Short on Storage condition [above|below] 16M line relieved.
The Short on Storage condition above or below the 16-megabyte line as indicated by the message has been resolved. Storage usage in the specified area has fallen below the Short on Storage detection thresholds.
Short on Storage condition [above|below] 16M line.
A Short on Storage condition exists above or below the 16-megabyte line as indicated by the message.
When storage usage exceeds 75% below the 16M line or 90% above the 16M line, the VNAC storage manager will no longer getmain storage in that area to satisfy storage requests. As a result, some VNAC agent functions or REXX execs may fail. This message indicates that there is apotential for this situation. It does not indicate that there is actually a problem, just that there may be if the storage usage does not fall below the threshold for the area.
By default, the VNAC agent will perform a system dump when this condition occurs but will continue to operate if possible. This system dump can be used by SDS to determine why the storage usage exceeded the threshold. Possible causes include a user program called from an automation exec getmaining storage but not releasing it when it terminates.
You can use the SOSSDUMP global configuration option to control performing a system dump when a Short on Storage condition occurs.
The default setting is to perform a system dump when a Short on Storage condition occurs. Note that the VNAC agent will only perform a maximum of one system dump per hour to avoid having a Short on Storage condition use all the available system dump space.
For more information about SOSSDUMP, refer to the GlobalConfig Parameters section in the VNAC Administer manual.
Dispatch of work to type tasks restarted.
The dispatcher has resumed scheduling work to tasks of the type specified–i.e. attended or unattended tasks. Work-scheduling was previously suspended because memory use below 16MB exceeded the maximum percentage allowed for those tasks. Work-scheduling resumed because memory fell below the limit and stayed there for the specified number of seconds.
Regarding configuration of the memory-use limits and the time to wait before recovery, see “Task Management” in the manual Administer VNAC.
Dispatch of work to type tasks suspended due to storage constraint.
Memory use below 16MB has exceed the maximum percentage allowed for VNAC tasks of the given type–i.e. attended or unattended tasks. The agent has stopped creating new tasks of that type. The dispatcher will not schedule new work to any existing tasks of that type until usage falls below the limit and stays there for the specified number of seconds.
Regarding configuration of the memory-use limits and the time to wait before recovery, see “Task Management” in the manual Administer VNAC.
Action: None.
