I've tried to figure that out, but it was nigh on impossible. The closest 
is that file descriptor, "10" but that doesn't mean much. I didn't see a 
filename.

It turns out that it wasn't *just* "\0\0\0\0" over and over -- there were 
some other escape sequences in there as well. But nothing that looked like 
"normal" data to me.

The box that is exhibiting this behavior is a build server. The error is 
triggered during a build of our product, during a test stage. The ossec 
component that freaks out is ossec-syscheckd.

Some things that strike me as notable:
* The build doesn't run in, or make changes to, any files or directories 
that are monitored by syscheck
* I have set the options for syscheck to 'report_changes="yes" 
realtime="yes" check_all="yes"' for all the files/dirs syscheck monitors

I don't really know what else to look at at this point so any 
troubleshooting pointers are welcome.

Thanks!
