From: Miles Fidelman on 14 Jun 2010 08:30 Anybody recognize this process name? I'm seeing a nightly crash, and this seems to be running at the time (I've been leaving top running in a window - deb_checkmd5sum seems to be at the top of the list each time the machine crashes). I expect it's part of a nightly cron job, but I'm (not yet) sure which one. Thanks for any pointers. Miles Fidelman -- In theory, there is no difference between theory and practice.

Compare the crash time with the cron jobs running/launched at that time to find out the "guilty pattern" ("/var/log/syslog" should tell).

From: Miles Fidelman on 15 Jun 2010 11:00 For educational purposes only: That's just a silly suggestion, beyond the obvious of searching for files named deb_checkmd5sum, of which there are none - doing a full text search on a terabyte of files is just too resource intensive. In any case, it turns out to be a procedure call inside Tiger - a somewhat aging security audit package. Turns out that Tiger runs an hourly cron job that, in turn, calls its own routine that parcels out tasks across different hours in the day. Buried way deep in nested config files (cron -> run.hourly -> tigercron) is a job that runs at 1am that invokes a Tiger sub-package called "check_system" - which in turns runs a procedure called "checkmd5sum" - which shows up in a process listing as deb_checkmd5sum (which, I think, comes from a library). We'll see if turning off that job stops the nightly crashes. I really can't believe there aren't better crash logging facilities for Debian.

I don't think it is silly. The volume of files in storage terms is not relevant; the number of files/directories (the complexity of the filesystem) is the issue which will impact how long the job takes to run. You can de-prioritise it below important tasks if you are concerned about impact. Before attempting this, though, you can search for files inside packages via http://packages.debian.org/. That is enough to prove that there are no official packages containing a filename ending in deb_checkmd5sum. > In any case, it turns out to be a procedure call inside Tiger - a > somewhat aging security audit package.

We'll see if turning off that job stops the nightly crashes. Interesting. I'd never heard of "tiger", but I see that it is packaged: http://packages.qa.debian.org/t/tiger.html > I really can't believe there aren't better crash logging facilities > for Debian. No need to disbelieve, there undoubtably are - we haven't even established what you mean by "crash" on debian-user yet. -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".
