/mcpexceeding the configured allowance of Lua instructions. When the amount of memory (as defined in the Memory Threshold field) or the number of Lua instructions utilized by this script (as defined by the Lua Instruction Threshold) exceeds an internal threshold, this alarm is triggered. For example, if the Memory Threshold is set to 100 kb and the internal threshold is 80%, this alarm will occur when this script has consumed 80 kb of memory. The internal threshold is not configurable and may fluctuate from Unified CM release to release. Another example: if the Lua Instruction Threshold is set to 2000 and the internal threshold is 50%, this alarm occurs when the script has executed 1000 Lua instructions. This alarm serves as a warning that resources (either memory or Lua instructions) have passed an internal mark where investigation into the consumption of those resources may be advisable to ensure the health of the script. Investigate and correct the resource issue before the script closes. When the values that have been configured in the fields, Memory Threshold field and/or Lua Instruction Threshold on the SIP Normalization Script Configuration window are met, the script closes and the SIPNormalizationScriptClosed alarm also occurs. For additional information when troubleshooting, check the SIP Normalization counter, MemoryUsagePercentage to learn the current resource usage. Recommended Action Examine the thresholds (Memory Threshold and Lua Instruction Threshold) configured in the SIP Normalization Script Configuration window and evaluate if those thresholds can be increased (take into consideration the CPU resources and memory when deciding to increase these values) or examine the script to determine if the message handlers can be written more efficiently to reduce the number of instructions in the script. Examine the script for logic errors. If the script is otherwise functioning normally but contains extensive logic, consider increasing the value in the Lua Instruction Threshold field. Be aware that more computing resources will be consumed as a result. You can also examine SDI trace files for additional details about this resource condition.
