Hi,

in a project we are using Fedora Commons 3.3 with PROAI for providing 
data to be harvested.
We have seen that in some situations the cache of PROAI is not 
syncronized with Fedora Repository: i.e. some Fedora objetcs in PROAI 
cache are not present or if present are not aligned with the related 
Fedora objects. This seems to be more probable when some Fedora objects 
which are in state D (deleted)  are again activated i.e. the object 
state is modified to 'A'. The modification date of Fedora Object is 
correctly modified. But the PROAI cache signals always deleted.
Peharps thre are some issues with proai.properties parameters 
configuration? E.g. we are using proai.driverPollSeconds = 600 and the 
other Back-End Update Behavior parameters are left with default values 
(proai.maxWorkers = 5, proai.maxWorkBatchSize = 10, 
proai.maxFailedRetries = 3, proai.maxCommitQueueSize = 120, 
proai.maxRecordsPerTransaction = 60, proai.driverPollingEnabled = true).

Thanks for your attention
