Issue



Clearwell Enterprise Vault collection finishes in 'Partial Success' and the following error is recorded in the Job Status Log: "The search failed due to a failure to search one or more of the targeted index volume sets".

 


Error



Error Code: 440878
INDEXING_E_INDEX_SEARCH_FAILED: The search failed due to a failure to search one or more of the targeted index volume sets.

Error searching archive name: JOURNAL 01, archive ID:ABCDEF0123456789ABCDEF1234567890EVJOURNALARCHIVE, Error Code:440878, Message:E_SERVER_UNAVAILABLE:The index server is not currently available

Error while searching JOURNAL01 EV01 - 440,878 - Error getting Search Result Property for Journal collection. Code:-2147352571, Message:Type mismatch.
- Got an unexpected exception from a searcher thread: [#422300] EV searcher error - 440,851 Searcher exited with non-zero error code
- Caught interrupt - killing searcher
- [#422300] EV searcher error - 440,851 Searcher exited with non-zero error code

 


Cause



The Clearwell Collection is overwhelming the EV Indexing server.

- Failure occurs when using a large quantity in the filter 'custodian mapping' for Enterprise Vault (EV) Journal collections
Example: 100 custodians

- Failure occurs when submitting thousands of archive volumes in the collection search criteria 

 


Solution



This is a known issue with Enterprise Vault 10 and is being researched. This error is written when the CollectionBroker.exe crashes on the EV server. 
(ETRACK: 2218405)
(JIRA: 28818)

RESOLUTION:
- If running 32-bit indexes (Alta-Vista version EV9), Set the registry key to a value between 10 - 30 (Default 10).
\HKEY_LOCAL_MACHINE\SOFTWARE|Wow6432Node\KVS\Enterprisevault\Indexing
Dword: MaxIndexServers
Value: 10 (Decimal)

This registry key must be created if not present.

For non 32-bit index environments (EV10 and higher)
- Separate the System page files from the Vault Service Account (VSA) temp folder onto different physical hard drives.  Also disable Anti Virus scanning on memory, the VSA temp folder and system paging files for all EV servers.  Reboot all EV servers to maximize memory availability prior to running the Clearwell collection.
- On the Clearwell appliance, throttling can assist in the effort to optimize search demands on the EV servers. Search response can be increased, search threads can be lowered and the search results batch size can be adjusted lower.

ESA PROPERTY CHANGES: (recommended settings)
esa.icp.ev.searcher.outputTimeout = 300000 (5 mins) to extend the timeout for an EV response.
esa.icp.collection.evsearch.MaxThreads = 8 (default 10), to throttle the threads for searcher.
esa.icp.collection.evsearch.BatchSize = 5000 (default 50000) to throttle the batch size
