OSGI Bundle Not Starting

We've recently been seeing this issue on a lot of AEM 6.1 instances where after a server restart, our custom and ACS Commons OSGI bundles will not start.  The status in the console is "Installed" and when you click to start, it logs the following error:

The only way we've been able to fix this is by manually deleting the .jar files from the "install" folders, then manually removing the bundle from the Felix console and finally re-installing the packages.  This will fix it until the server is shut off again, and next start the bundles will go back to "Installed".

Does anybody have any clue what could be going on?
