Problem summary
**************************************************************** USERS AFFECTED: Java and fully managed .NET clients that call inquire() or MQINQ() methods are potentially affected, based on the parameters passed. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: The MQ 9.1 SVRCONN channel agent incorrectly produces a protocol error FDC record if the passed IntAttrCount parameter is greater than the passed SelectorCount parameter, in previous releases the SVRCONN agent would attempt to process the inquiry request.
