DB2 - Problem description

Problem IC74404 Status: Closed

POTENTIAL HANG IN GATEWAY ENVIRONMENT DURING APPLICATION INTERRUPT

product:
DB2 FOR LUW / DB2FORLUW / 950 - DB2
Problem description:
There is a potential hang in a gateway environment during an 
application interrupt. 
 
The symptom includes the gateway instance agent holding the 
m_appServLatch latch while appearing idle.  However, if the 
agent is in the tcprecv function call, it may be waiting for a 
response from the remote instance.  If something interrupts the 
response, the agent holding the latch may wait indefinitely. 
 
A potential stack for the agent holding the latch: 
tcprecv 
sqlcctcprecv 
sqlccrecv 
sqljcReceive 
sqljrDrdaArInterrupt 
sqleInterruptGatewayAgent 
sqeAgent::InterruptAgent 
sqleInterruptApplication 
sqeAppServices::InterruptAppByIndex
