Error description
An abend of the Admin Agent process is observed when updating the deployment log after a change request is issued on a broker which has many execution groups and message flows. In this instance the customer issued the mqsichangeflowstats command to enable stats for all message flows in all execution groups. This generated over 2000 deployment log entries which were not handled correctly by the Admin Agent. An abend stack similar to this may be observed: ImbDeployManagerCache::addLogEntries(std::vector<ImbWstring, ImbDeployManagerCache::refresh(ImbQueueManager&) ImbDeployManagerCacheRefreshThread::refreshCache(ImbQueueMan ImbDeployManagerCacheRefreshThread::run(ImbOsThread*) ImbThreadPoolThreadFunction::run(ImbOsThread*) ImbOsThread::innerThreadBootStrapWrapper(void*) ImbOsThread::threadBootStrap(void*) threadBootStrapWrapper
