Problem
You attempted to use the prune command on my Master UCS to reduce the size of the translog database because the translog database has reached almost 87% capacity (of 16GB).
The initial attempt to keep only 1,000,000 entries fails with:
[...]
Traceback (most recent call last):
[...]
result = func(*args,**kwargs)
ldap.SIZELIMIT_EXCEEDED: {'desc': 'Size limit exceeded'}
Solution
This is a bug which has been fixed with UCS 4.4 e146. Upgrade to the latest version of UCS.
