SYMPTOMS
When starting a large number of print sessions simultaneously on SNA Server, status updates may not be reflected properly in SNA Manager, which may indicate that printers are unavailable when in actuality they are functioning properly.
Event Viewer may also show the following event log:
Event ID: 12 Source: SNA Print Server The Buffer pool for messages has become exhausted. Data may be lost.
Internal tracing may show the following:
aimmain.c(1450) AGFQH Free Queue is EMPTY!
aimctrl.c(972) AStus Status message lost
aimctrl.c(1005) AStus Leave, rc=5
CAUSE
There is a limited queue of resources used internally to send Manager status messages, and these are getting used up faster than they are being freed.
