Description copied from interface: StorageEventLogger

Note that not all Throwables are Exceptions. There are also Errors. And not all exceptions are problems. There are also program execution control vehicles like InterruptedException. The actually fitting common term is "Disruption". Throwable is a very low-level technical, compiler-oriented expression.

Specified by:

logDisruption in interface StorageEventLogger

Parameters:

channel - the affected channel

t - the reason for the disruption
