Hi,
This is a slave polling the master for its index version but it seems the
master fails to respond.
From the javadoc:
public class NoHttpResponseException
extends IOException
Signals that the target server failed to respond with a valid HTTP
response.
Cheers,
I see a large number (~1000) of the following executeWithRetry messages in
my apache catalina log files every day (see bolded snippet below). They
seem to appear at random intervals.
Since they are not flagged as errors or warnings, I have been ignoring them
for now. However, I started wondering if INFO message is a red-herring
and thinking there might be an actual problem somewhere.
Does anyone know what would cause this type of message? Are they normal?
I have not seen anything in my google searches for solr that contain this
message
Details:
1. My CPU usage seems fine as does my heap; we have lots of cpu capacity
and heap space
2. The log is from a searcher but I know that the intervals do not
correspond to replication (every 15 min on the hour)
3. the INFO lines appear in all searcher logs (we have a number of
searchers)
4. the data is around 10m records per searcher and occupies around 14gb
5. I am not noticing any problems performing queries on the solr (so no
trace info to give you); performance and queries seem fine
Log snippet:
