Running 'sync' command frequently.
I have a Linux server that runs a Java based app that automates file transfers for a large number of users/systems. I'm running into a problem with the scripts for this automation program in that when I have a function in the script generate an output file, and the next line requires that file to be present; the script will fail because the file hasn't made it to disk yet. I've figured out some workarounds for this problem. I can either enter a sleep/delay command to delay the whole script for a few seconds giving the system/java a few seconds to write the file to disk; or I can run a sync command that will immediately write the file to disk.
My question is, could there be any undesired side affects to running the 'sync' command so often on a system?
