Good day.
I'm a recent convert to aptosid, coming from Ubuntu. I can say that this distro satisfies the tinkerer in me. What's even better is that I get to stay on the edge, with a little caution of course. I also came upon Linux Mint Xfce RC, but 0.93GB iso download vs. 430MB iso, aptosid is the best deal for me, considering that the iso would be easily outdated because of a rolling release. I like my distro lean and fast, without the fats. 
On to my report. I'm noticing 100% cpu usage on one core whenever famd is running. Waiting for a considerable amount of time doesn't make the process terminate normally, so I had to kill it. I'm unsuccessful in finding indications of it misbehaving in the log files, actually no indications are made relating to famd, or even at my .xsession-errors log.
I have recently upgraded my 2011-01 aptosid install, running Linux 2.6.38-2.slh.3-aptosid-686 #1 SMP PREEMPT Tue Apr 5 17:47:34 UTC 2011 i686 GNU/Linux on a Pentium 4 631.
Searching the forums yielded no results relating to my issue. I'm considering disabling the service entirely but I'm not sure how this would impact the system, or parts of it. Could somebody have any hint on this? Would disabling the service be advisable workaround?
Versions:
fam-2.7.0-17
libfam0-2.7.0-17

| Well I didn't specifically install it on purpose, and I may have missed seeing that being given as part of some software packages I recently installed, but I doubt that. |

Thank you for the suggestion.
I'm wondering, since I didn't specifically installed FAM, why this came with the install instead of Gamin, which describes itself as
Quote:
Gamin has been designed as a drop-in replacement for FAM with security
and maintainability in mind and can use Linux's advanced inotify
service when available.
Perhaps I will do this instead.
UPDATE:
I’m not sure why Fam would be used in aptosid instead of Gamin. As a workaround I opted to replace it with Gamin, and I have several things to say about this:
1) If I manually remove fam and libfam0 packages then this will remove other packages as well. Simulate the removal process first to see if this is acceptable. However,
2) If I install gamin and libgamin on top of fam and libfam0, then those other packages will not be removed, save for libgnomevfs and thunar-vfs and fam. It really seems that Gamin is indeed a drop-in replacement for Fam, because removing Fam removes a couple more packages, while installing Gamin on top of Fam will remove Fam but not the others.
These observations are done on aptosid Xfce. Not sure how things are with KDE and Fam. |

well, over the years, fam and gamin both had their problems (eating up CPU).
so, use what works ok at a given time on given hardware.

I have seen fam do this a few times. Once it did it when I had disabled it at boot and started it manually later. It did it repeatedly so I had to reboot. Then it also did it once when I was testing updates to pcmanfm-mod (which uses fam or gamin).
If you're not using a program which relies on fam, it can be disabled. You'll know if you need it because a program like pcmanfm-mod won't be able to detect changes in the folders.
Code:
# disable at boot
update-rc.d fam disable
# re-enable at boot
update-rc.d fam enable
As for fam vs gamin, I had gamin installed on Arch Linux and was told it was better than fam. But I find fam works better in pcmanfm-mod than gamin did - changes are detected instantly whereas there was a delay with gamin. There could have been other factors, but in general fam has been working well for me. |
