Error description
Communications Server for AIX and Linux, Version 6 -------------------------------------------------- Communications Server logs messages that indicate a memory shortage. For example: 512-63 Not enough memory to activate link. 512-114 Not enough memory to generate link Alert. 512-72 Not enough memory for orderly link deactivation 512-79 Not enough memory to forward Alert Snaadmin commands return very slowly or not at all or fail with error "cannot allocate memory".
Local fix
Stop and restart the SNA software.
Problem summary
USERS AFFECTED: All PROBLEM DESCRIPTION: The server becomes unusable because the kernel buffer usage has gone beyond the maximum (90%) as reported by the command "snaadmin query_buffer_availability". Kernel memory usage is also elevated. PROBLEM SUMMARY: Following an extended period of waiting for a reconnection to the mainframe and a window condition, the product can queue up many thousands of NMVT Alerts which are useed to report the connectivity failures. These are release if the NMVT PU (the first link connected) is deactivated at a later time.
Problem conclusion
The code has been modified to limit this queue to 128 messages. This is sufficient for reporting errors, as subsequent events occurring while messages can not be transmitted would typically be duplicates of the initial failures. These Alerts correspond to messages logged in the Communications Server error logs.
