Re: Read Waiters growing

I see a strange thing in cn=Monitor. Suggestions needed.
I have a huge database, and performance is great as long as olcReadOnly
But a soon as I enable writes, the number of Read Waiters are growing,
even though there's no or very few Write waiters.
# Read, Waiters, Monitor
# Write, Waiters, Monitor
# Current, Connections, Monitor
I have idletime=120 and connections do around 30 reads each before they
are retired, but not many writes. Like this:
# Connection 5389, Connections, Monitor
dn: cn=Connection 5389,cn=Connections,cn=Monitor
It's slapd 2.4.21, BDB 4.8.26 and back_bdb.
Any hint to what could cause that many read-waiters, but only while
writing is enabled and even though there's not that many writes?
It could be a bug in back-monitor...
