While trying to upgrade my f15 test vm with the ipa 2.1 release candidate ipa-ldap-update hung and prevented the install from proceeding. Note, yum was upgrading a lot of new packages at the time including 389-ds, pki-code, xmlrpc-c curl, all the ipa packages, etc.
The ipaupdate.log file showed this as the last entry:
INFO Creating task to index attribute: memberHost
Rich M. examined the 389-ds logs and logged in and attached to the 389-ds process in gdb to diagnose but was unable to ascertain anything (in part because the 389-ds debug packages were not installed.
We also tried to perform an ldap search using ldapi (because during the update ports are turned of) to examine the tasks, but after 389-ds authenticated the directory manager the ldap search also hung.
backtrace of all threads in 389-ds when hang occurred 58478.txt
This seems to be related to https://fedorahosted.org/freeipa/ticket/1635
Risk seems low enough that not changing our plugins to use pthreads RW lock is acceptable for now, pushing to 2.1.1.
The 389-ds team is working on a fix for the memberOf plugin.
Rich thinks there is still a remote possibility of this happening but much less so since Nalin switched to pthread read-write locks. The IPA plugins changed as wel.
Keeping open for now but risk is considered low.
Dropping priority and pushing to 3.0. This is mostly a tracker to await 389-ds modifying its internal read/write locks.
This has not been seen since its first report. Closing until it is reproduced again.
