zend_optimizerplus.force_restart_timeout
The Optimizer+ uses this directive to identify a situation where there may be a problem with a process.
After this time period has passed, the Optimizer+ assumes that something has happened and starts
killing the processes that still hold the locks that are preventing a restart. If the log level is 3 or above, a
"killed locker" error is recorded in the Apache logs when this happens.
