Syncrepl error causes consumers to freeze
Hi,
I am using 2.4.26 on syncrepl master (provider) (package on CentOS 5.7
x86_64) and 2.4.22, 2.4.26 on two consumers respectively.
Last night, I edited a user account (hosted in LDAP) and when this tried
to replicate to two consumers, both froze. This did not happen on
another consumer (also 2.4.26) which was using replication over the
Manager account. The two ones which froze are using a limited-privileged
BindDN for replication which does not have access to user accounts (so,
the user account should/would not be replicated on those two consumers).
On the master:

I have not seen this behavior in months and months of use.
Any advice?
Thanks,
