Error description
The RECLAIM_SOCKET routine in DFHSOPL tries to iterate over the socket pools to find a socket that can be released for use. If no pooled sockets are available, DFHSOPL loops until the runaway cancels the task. Loop happens because the first pool is checked and instead of moving on to the second pool and then finishing, the first pool is checked again and again.
Local fix
code Socketclose(0)
Problem summary
**************************************************************** * USERS AFFECTED: All CICS users. * **************************************************************** * PROBLEM DESCRIPTION: DFHSO0001 An abend (CODE ---/AKEC) has * * occurred at offset x'FFFF' in module * * DFHSOPL. * **************************************************************** * RECOMMENDATION: * **************************************************************** Outbound HTTP connection pooling is being used in CICS. When CICS is at the MAXSOCKETS limit another socket is required for a new request. DFHSOMG calls DFHSOPL for function RECLAIM_SOCKET to try and release a socket from a connection pool that is not currently being used. DFHSOPL attempts to scan through all the available socket pools in turn trying to locate a suitable unused socket to close. The socket pools are all empty at this time and there are no sockets available to reclaim. This condition causes DFHSOPL to enter a loop repeatedly trying to locate a socket in the first socket pool. The loop is eventually terminated by the runaway timer and message DFHSO0001 is issued.
Problem conclusion
DFHSOPL has been changed so that it no longer attempts to reclaim a pooled socket when the socket pools are empty.
