Error description
Reported Release: 623 FP2 When the maximun size of the directory is met for KHD_TOTAL_HIST_MAXSIZE, the error message that is traced in the Operations Log and Universal Message Log overruns the message buffer which is only allocated for 128 characters. This causes the stack to be corrupted which affects the unlocking of the short term history file and a dead lock occurs on the shortterm history file. RECREATE INSTRUCTIONS: Set KHD_TOTAL_HIST_MAXSIZE and see if the trace log shows that the lock on the file is not released for the short term history file. For this customer the short term history file was UNIXDPERF. This failure will be driven by the size of the short term history file name and how much of the stack is overrun. So, it may not cause the failure for deadlock if the lock flag is not affected.
Local fix
