Package: obnam Version: 1.19.1-1 Severity: normal obnam grows in size to fill all 2 gb of memory on the system and OOMs. Memory use seems to increase the more files are backed up. I did try setting lru-size to half of the default, but this did not change much memory use.
I have a meliae profile of a backup of 100k files, most of which are unchanged from the previous backup, which shows memory growing pretty steadily over time. Since the log and profile files contain filenames, I don't want to publish them here, but can send them on request. (500 mb of compressed log files).
