IAZ0538I server_name Storage not obtained for inbound requests
Explanation
The system tried and failed to obtain storage for the IAZCMTST and IAZCSOCK data areas for an inbound socket connection request.
The NETSERV address space limits the number of connections allowed in a single address space based on the size of the available private storage region when the address space starts. When installation exits that get control in the NETSERV address space use significant amounts of private storage or fail to free storage after it is no longer needed, this condition can result in a storage shortage.
- server_name
- The NJETCP server name.
System action
All requests to create an inbound socket are suspended until the storage shortage is relieved.
Operator response
If this condition persists or repeats frequently, notify the system programmer.
System programmer response
If the address space only has problems when it has run for a long time and the number of socket connections remains constant, the problem is most likely to be related to storage leaks. Examine the dump for storage leaks associated with data areas obtained in installation exits. If the problem appears to be related to a storage leak in IBM® code or the NETSERV allowing more connections than the address space can support, obtain the X'EC8' abend dump and other relevant documentation, and contact the IBM Support Center.
If the address space only has problems when the level of activity reaches a certain level and the problem goes away when the number of active sockets is kept low, it is mostly likely that installation exits require significant amounts of storage. You may need to use an additional NETSERV address space to handle the number of connections.
