Description Tobias Burnus 2006-03-17 20:46:34 UTC

I installed a package manually and while running the post-inst script, ZMD interfered (3 packages, 3 times; rpm: "waiting to reestablish exclusive database lock"):

rpm -Uvh kernel-* tpctl-kmp-default-4.17_2.6.16_rc6_git1_2-18.i586.rpm

can we stat less often or back-off in some fashion?

Comment 2 Dan Mills 2006-03-24 22:34:12 UTC

Ok, I committed a change to zmd so that it waits 30 seconds after the last time the db was changed before it emits the InstalledPackagesChanged event (which is what triggers the reload).  Committed in svn r26201.

Comment 4 Matthias Hopf 2006-03-27 10:19:45 UTC

Note that this could trigger a race condition (if a package is to be installed with zmd or whatever, inside that 30 seconds interval after one has been installed with rpm).
This very much depends on the internal architecture, though.
