IV16584: CRASH IN SNA_V5ROUTER64
A fix is available
Closed as program error.
Communications Server for AIX, Version 6.4 ------------------------------------------ Crash in sna_v5router64 during startup at boot time.
USERS AFFECTED: All users. PROBLEM DESCRIPTION: During a failed startup of SNA at bot time, the kernel crashed with a stack showing the logging function vll_router_write_log_to_buf called from vpr_stream_open. The problem was seen when snatpsrvd is attempting to issue an open to the logger function in the kernel, but any of the SNA processes could trigger this. The dump showed that the snaerrlog process was no longer running. PROBLEM SUMMARY: There is a very small window where the logging code has been initialized and then terminated while a log entry is being generated.
Additional locking code has been added to protect against this window.
