Versions Affected:

Problem was discovered in version: R9.1b
Problem is fixed in version: R9.1d

Resolved In Version:

Problem is fixed in version: R9.1d


Symptoms:

Host communications to a controller may become unresponsive when a persistent string table is accessed and background downloading is actively used. In some cases, this may also affect a standard chart within the strategy. For example, if the strategy is stopped, a non-host task chart may continue to show it is in the RUN state because it is stuck trying to access a persistent string table element.
