Probably, because mmt keeps all entries in memory. Florian suggested to just omit the "no error" entries.

ash is under heavy load (and even omitting "no errors" did not help). Only after deleting some errors 54819 entries are now left.

By clicking "reload" while loading the following crash can still be provoked:
12:03:10.92 error: (server) error in underlying server: class java.io.IOException:Broken pipe

it only helps to keep the load low.
