I'm wondering the following things:
- Is it possible that one of the ITS's for syncrepl that will be
included in 2.3.42 would address this crash? Any suggestions on tracking down why it crashed?
You may have hit the accesslog callbacks bug (ITS#5490).
Looks likely. Then, I need to research why I didn't get a core file (likely a ulimit problem)
- Does it appear that I have a configuration problem (the
delta-syncrepl taking about five times as long to get the changes out to the replicas as it took to apply them on the master)? Where would you suggest I look if it is likely?
Have you set up a DB_CONFIG file for your accesslog DB that's reasonable?
I think it's reasonable ;-) I have two DB's and 4GB of memory on this system. The DB_CONFIG for the accesslog DB is as follows:
set_cachesize 0 524288000 2 set_lg_bsize 2097152 set_lg_regionmax 262144
Have I missed something that would be more reasonable?
I don't know without knowing the size of your accesslog db. ;)
Personally I avoid splitting memory regions if possible, but that may only apply to BDB 4.2.52, I've never tested that aspect of configuration with anything more recent.
