As Turbo J said, the SREQ bit is set after reset triggered by the application calling NVIC_SystemReset() function. This typically happens in the error handler, triggered by an error code passed to APP_ERROR_CHECK, an assert, or a hardfault.
If you define the DEBUG flag in your preprocessor symbols, the error handler will print the cause of the error on the log, before entering an endless loop instead of triggering a soft reset. You can get similar output from the HardFault handling library if you include this in your project.
