Hi,

With script provided by Rich, I looked at my db cache usage and it does not
look to be high enough

# under each db are the list of selected indexes specified with INDEXLIST
       dbname      count          free  free%    size
changelog:ent          5       2076333   99.0  4163.8
changelog:dn       15976       9303557   88.7    74.0
 userroot:ent       4763     175321074   83.6  7221.1
 userroot:dn        4763       9995056   95.3   103.0
    ipaca:ent        425       6337866   60.4  9759.8
    ipaca:dn         425      10451081   99.7    81.6

Right now I set it to 200MB. So, I am planning to bring it down to 100MB

Also, *nsslapd-db-checkpoint-interval *will change it to 80 or 90 from
default of 60

I will check this out and the impact it has on the hang issues and get back

Thanks
Rakesh
