We do see occasional binary characters in the logs - but somehow this is only
an issue in one of our Solr environments.
A colleague pointed out that grep has an option for binary files. Just tried
that manually and it seems to work, so I may end up modifying our bash scripts.
Thanks,
Jay

What comes to my mind is the following: and there do indeed seem to be control
characters added whenever Solr start running
[16:33 solr10 1435]$ strings solr.log | diff - solr.log | less

Subject: [EXTERNAL] log file appears binary
Hi -
We have multiple Solr 9.5.0 installations running on Linux. All are configured
the same.
On one of those installations, when I grep the solr log, it returns "Binary
file solr.log matches".
The "file" command returns "data".
I can edit or cat the log file and it looks like regular text.
We have bash scripts that grep the solr log, and so these scripts don't work on
this particular installation.
I tried adding charset="UTF-8" to the PatternLayout in the log4j configuration
file. That did not help.
Any ideas what may be going on here?
Thanks,
Jay
