Re: This is a new thread

This has nothing to do with that thread, but has been worrying me:
Our production RHAS4 site with 4 OpenLDAP 2.3 servers (1 delta
syncrepl provider, 3 consumers) has been running exemplararily (new
word?) since ~= 2.3.27.
All servers were running 2.3.33 perfectly, then I built 2.3.34 and on
just one of the servers (the master), after around 4 hours of it doing
hard work, I see (top) the slapd process consuming 98-99% CPU. The CPU
consumption is never relinquished, even if I wait for hours (ouch). If
I reinstall 2.3.33 this goes away and all is back to normal.
For this, absolutely, make sure you have debug symbols, attach with gdb
and get a stack trace for all active threads.
On my test machine:
I reinstalled the 2.3.33 rpms, then simply copied the
/usr/sbin/slapd (made a backup first). It seems to run ok with the
2.3.33 libs, or do I need the 2.3.34 libs too? Whatever i do on the test
rig I have to replicate on the production master/provider. I'm loathe to
reinstall the whole 2.3.34 gamut on that machine, I'd rather be able to
copy the 2.3.33 slapd back, if I get problems (the production provider
does failover to a slave/consumer if slapd goes down, so short outages
shouldn't be a problem).
For the OpenLDAP 2.3 rpms I'm using Buchan Milne's 2.4.24 srpm spec
file, basically only modified each build for the version, so that all
the %prep, %configure and %build stages are the same for all builds -
irrespective of OL version.
Ta in advance,
Quite far in advance, we're only on 2.4.4 here.
Yeah :( sorry for the typo ...
