Error description
For each TLS connection, a small amount of memory is not released. If there are a large number of connections/disconnections, the memory usage of the amqrmppa process can increase rapidly. Using the "strings" shell command on a core file taken from the amqrmppa process may show many occurrences of the string "extended master secret".
Local fix
Manually upgrade the GSKit installation that IBM MQ uses to version 8.0.55.20 or higher.
