--------------------------------------
Summary: Facing unsafe memory access operation error while calling
searcherManager.maybeReopen()
Key: LUCENE-7527
URL: https://issues.apache.org/jira/browse/LUCENE-7527
Project: Lucene - Core
Issue Type: Bug
Components: core/search
Affects Versions: 3.5
Reporter: Jagmohan Singh
We are getting below error while calling searcherManager.maybeReopen() method.
We are using MMAP to read NFS index directory mounted against 3 servers. We
have a different process to update the indices and have 3 processes to read
from the index. What we believe it when we face this error in one of the
readers is due to heavy writes int he indices which are happening at that time
and MMap implementation is not able to coop with it..
Caused by: java.lang.InternalError: a fault occurred in a recent unsafe memory
access operation in compiled Java code
