Re: (ITS#4738) hdb livelock

Please visit https://www.nbcs.rutgers.edu/~richton/richton-20061107-livelock_2.txt for an updated backtrace. This one almost looks like it has lock contention, and a writewaiter assert is notably missing... I'm going to rm the bad link, it can only hurt people.

Sigh. As may be obvious to anybody unfortunate enough to look at the link, I seem to have gotten my core files confused. I have a bunch of db_stat -CA done properly, but the backtrace for this may be lost to the bit bucket. I'll poke around my systems and see what I can find, but I think it might be nothing. A syslog of "waiting for 1027 threads to terminate" might be the only other durable evidence.

(ITS#4738) hdb livelock
by richton＠nbcs.rutgers.edu 07 Nov '06

07 Nov '06

Full_Name: Aaron Richton Version: 2.3.28+4720 OS: Solaris 9 URL: https://www.nbcs.rutgers.edu/~richton/richton-20061107-livelock.txt Submission from: (NULL) (128.6.31.137) See also ITS#4720, although this is slightly different. hdb livelock (CPU 100% gunned) on 2.3.28 with patch for ITS #4720 (syncprov.c 1.161 -> 1.162 diff). See URL for backtrace and db_stat -CA of the database on threads t@13 and t@16, which (if I'm reading correctly) are the affected ones. I have the db_stat -CA of the other backends saved if I misread, and the core file available if variables are needed. Aside, I know you're looking for RE23 testing, I was kicking the tires of that and about to put it up when this happened. Soon I'll be there, regardless of how this turns out, due to writewaiter concern.

I suggest you read at least slapd.conf(5) (but I suspect you need to read more) before considering the possibility of a software bug. This ITS will be closed. p. Ing.

Added module = pathto/smbk5pwd.la and overlay = smbk5pwd >slapd fails with "overlay smbk5pwd not found" While there is no indication that this behavior is due to a bug in OpenLDAP Software and 2.2 is Historic, there seems this report should be closed. If you believe this behavior due to a bug in OpenLDAP Software, I suggest you duplicate it in the latest 2.3 release and then file a new bug report that elaborates on why you believe the behavior is due to a bug in OpenLDAP Software.

There have been no changes to the connection management since 2.3.27, so it makes sense that the traces look the same. A number of fixes have gone into HEAD along these lines, but they haven't been backported to RE23. -- -- Howard Chu Chief Architect, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc OpenLDAP Core Team http://www.openldap.org/project/
