Noticed that /var was 2.2G (out of 8G disk). Looked further and saw that /var/log/messages was 2.2G.

Version-Release number of selected component (if applicable): pulseaudio-0.9.21-1.fc12.x86_64 How reproducible: Have not yet tried. Additional info: When the messages file finishes compressing, I'll reboot the VM and see if the problem occurs. This VM was just created yesterday.

The host is also Fedora 12 with all available stable upgrades. No pulseaudio problems on the host, just in the VM. The VM also has all available Fedora 12 stable upgrades. I'm more than willing to post whatever information is required, if you are available to help. It seems like a serious bug to me if pulseaudio is allowed to fill up the partition hosting /var/log/messages. In my case, this is the root partition, and it filled 2.2G in around 45 minutes.

I have had to clear my log files 3 times now in the past day because my root filesystem was full, which started breaking various things (like my postfix installation which gets my mail delivered directly to me). The log files are available on request privately, they contain information that I do not want published on the bug report, and due to their size, I cannot be sure to filter them and not accidentally remove anything relevant. There may be more in the log files than I have seen, simply because of the amount of stuff there. For anyone who requests the files, I'll email them: note that the log files are to 4 MB. However, they will expand to somewhere around 9 GB; compression on my system (4x 2.2 GHz 64-bit cores) took 300 minutes each, compressing with pbzip2. If you have a multiple-core system, decompression will go a lot more quickly if you use pbzip2 instead of bzip2 (and note also that compression took about 5 hours, I'd expect decompression to be similar). I will attached trimmed-down versions of these files as well, shortly after uploading the full log files. This bug causes denial of service of anything in /var or on /, so I am classifying this as a security bug.
