Problem with interaction of open3, sysread and DBI (pg)

I have a strange issue with sysread and postgres (and ffpeg/stderr) If the main program throws an error sysread stops if I write to the database (a log table) this is the program (need open3 because ffmpeg writes to stderr not stdout) use IPC::Open3; my($file,$in, $out); my $pid; use Symbol 'gen

Open and perl sub

Is it possible to have the output of a perl module piped to open (open3 in my case), so I can use a file handle contains the output passed to sysread Odd question I know Thanks
