Hi,
When I run logstash 6.4.1, there are lots of follow error logs.
[ERROR][filewatch.tailmode.handlers.grow] read_to_eof: general error reading /home/11thone/caselog/logmonster/CAS-HUNAN-TEST/MME01/MMDU0/SubsHandlerSnapshot7.log {"error"=>"#<SystemCallError: Unknown error (SystemCallError) - /home/11thone/caselog/logmonster/CAS-HUNAN-TEST/MME01/MMDU0/SubsHandlerSnapshot7.log>", "backtrace"=>["org/jruby/RubyIO.java:2958:in sysread'", "/home/11thone/elk/logstash/vendor/bundle/jruby/2.3.0/gems/logstash-input-file-4.1.6/lib/filewatch/watched_file.rb:224:infile_read'", "/home/11thone/elk/logstash/vendor/bundle/jruby/2.3.0/gems/logstash-input-file-4.1.6/lib/filewatch/watched_file.rb:236:in read_extract_lines'", "/home/11thone/elk/logstash/vendor/bundle/jruby/2.3.0/gems/logstash-input-file-4.1.6/lib/filewatch/tail_mode/handlers/base.rb:52:inblock in controlled_read'"]}
is there some config error in my logstash or system. or just the grok error?
