Description

When trying to start a non-existent service, procrun will write an enormous amount of null bytes to stderr. Since these are not printable, the problem is not normally seen in a terminal. However, if a wrapper script is used that captures stdout/stderr, the output file is over 8 GB.

Reproducing is quite simple:

prunsrv.exe //ES/my-dummy-service 2> test.err

The file test.err then has 8589934985 bytes. The printable characters are only a few lines of warn/error log messages.
