Symptoms

Issue is that an iScript which uses out of box function hashClear consumes too much memory and does not release memory while reloading data by semaphore. It was observed that loading data by iScript having this function takes more memory (even if reading from the database during startup). As a result, pipeline shuts down due to reaching 95% memory utilization (memory monitor has been set).


Steps to reproduce:

1. Comment hashClear function in the iScript
   1. Start pipeline
   2. Check memory
   3. Reload iScript using “ifw.Pipelines.PRE_PROCESS.Functions.PreProcessing.FunctionPool.Map_IMSI.Module.Reload {}”
   4. Stop pipeline
2. Uncomment hashClear function in the iScript
   
   1. Start pipeline
   2. Check memory
   3. Reload iScript using “ifw.Pipelines.PRE_PROCESS.Functions.PreProcessing.FunctionPool.Map_IMSI.Module.Reload {}”
   4. Compare results

Notice that memory consumption in case 2 is higher.
