Description Neil Darlow 2005-01-28 07:02:21 UTC

I have anacron and vixie-cron installed in 2004.3.

I have been receiving a number of e-mails at cron.daily run time relating to bzip2 and hard-linking errors during the updatedb run.

On running a ps ax during the cron.daily run, I observed two instances of run-parts cron.daily executing updatedb.

Looking at the header of /usr/sbin/run/parts, there appear to have been some locking and race conditions in the past. It appears there may still be some more unresolve ones.


Reproducible: Sometimes
Steps to Reproduce:
1. Have anacron run at boot
2. Execute a ps ax during the updatedb state
3. Observe multiple instances of run-parts cron.daily and updatedb

It is possible for two occurences of cron to run at once (atleast used to be).
Old servers that I used to maintain having large cronjob-scripts, we always did
locking manually in the script.

This depends onto 26392: until that is fixed, this won't work.

People, anybody fixing _a bug_? The base bug is trivial to solve (scripts have 
been supplied)... What are you waiting for?

well - we reencountered this same problem once again and are working towards a solution on bug #235174. sorry about the gross delay...
