Re: Slaves taking up 100% cpu
Hi all,
Thanks for the replies (and discourses on stability versioning =).
We are already in the process of testing out OpenLDAP 2.1.25 and BerkeleyDB
4.2.52 (with that one patch they have available). In the meantime though, we
are stuck with OpenLDAP 2.1.22 with BerkeleyDB 4.1.25 (the accompanying
patch, btw, seems to only have an effect on databases that include indices,
but I may be wrong).
I was hoping that someone would be able to spot an obvious (or non-obvious)
configuration flaw on my part that would explain the behavior exhibited in
the db_stat output and the 100% cpu usage. Like perhaps an idea on why this
only happens to a slave, or if there is a change that I can make
configuration-wise that will fix or alleviate the relatively high number of
locks being held, etc.
I know it's a PITA to read through all that debugging information (which is
why I summarized the differences), but any help would be greatly
appreciated. Of course, I realize that nobody here is paid to answer other
people's questions. =)
Thanks.
