Just as a sample, SolrCore contains blocks like
} catch (Throwable e) {
SolrException.logOnce(log,null,e);
}
And SolrServlet:
} catch (Throwable e) {
SolrException.log(log,e);
sendErr(500, SolrException.toStr(e), request, response);
}
What will happen with OutOfMemoryError? If memory is not
'enough'-enough it won't even output to catalina.out, and JVM/SOLR
will stop responding instead of 'abnormal' exit...
Quoting Fuad Efendi <[EMAIL PROTECTED]>:
I suspect that SolrException is used to catch ALL exceptions in order
to show "500 OutOfMemory" in HTML/XML/JSON etc., so that JVM simply
hangs... weird HTTP understanding...
Quoting Fuad Efendi <[EMAIL PROTECTED]>:
Following lines are strange, looks like SOLR deals with OOM and
rethrows own exception (so that in some cases JVM simply hangs instead
of exit):
