At the end of multi-process loadHier, the hierdatacleaner private utility is called in multi-process mode. In the case of a large domain, one or more sub-processes may error out with lock timeouts on changearray.db or shadow.db of the master domain. The following error occurs:
Steps to Reproduce:
This is difficult to reproduce and is based on the number of positions being purged or reclassed in a particular load. The following steps will increase the chance of the issue happening.
1. Set the RPAS_LOCK_TIMEOUT to a shorter interval than 60000. For example, 3000.
2. Create either a large number of reclass loads or purge a large number of partitioned positions without purging the full domain.
3. Run loadHier with processes > 3.
4. LoadHier will succeed, but check the hierdatacleaner log in the output for errors.
