I'm not sure exactly when the file is considred large but I think it is when the uncompressed files are > 2GB. gzip fails silently. zcat will just show the first part of the file. gunzip will expand the first part of a file then remove the .gz file, effectively deleting a lot of data - again producing no error message. >How-To-Repeat: zcat or gzip a large file...I have a large number of log files whose uncompressed size is 2 - 4GB that all seem to exhibit the behaviour. >Fix: The gzip from the ports collection doesn't seem to have the problem so I'm assuming its been fixed in later versions of gzip. Perhaps the version in the base system can be upgraded.
