Hello, After upgrading to v3.2.0, amstatus intermittently generates the following warning messages followed by a status report that is not consistent with amreport or amoverview reports of successful competion.

I can confirm this.

I've read that there is a patch already commited. But it would be nice, if a
developer could provide a patch for downloading, because I don't know how to
get it for the current version from the repository.

The amdump log file is corrupted.
The attached patch fix it for newer log.
