Emmanuel Lecharny commented on DIRSERVER-1556:
----------------------------------------------
(Sorry for the late answer)
I *think* the issue can com from the way we deal with BitString AttributeType
(x500uniqueidentifier), which, in some cases, might require an extra byte to
store the number of unused bits in the last bytes.
In this case, we will allocate a PDU one byte short, thus the error message.
The BitString class has been fixed 2 weeks ago, it should now work better, but
it's in trunk.

> Key: DIRSERVER-1556
> URL: https://issues.apache.org/jira/browse/DIRSERVER-1556
> Project: Directory ApacheDS
> Issue Type: Bug
> Affects Versions: 1.5.7
> Environment: Windows Server 2003 SP2 / Sun JRE 6 update 21
> Reporter: Ewald Wasscher
> Priority: Critical
> Fix For: 2.0.0-RC1
>
>
> We're currently testing Apache Directory Server (ADS) in a custom environment
> for a customer of ours. In this environment ADS is used to store certificates
> and certificate revocation lists. At first everything seemed to be working
> fine, but we encounter an error that seems to randomly occur every now. When
> adding an object, viewing an object in Directory Studio or adding attributes
> (the certificate) to an existing object this fails with the following message
> in apacheds-rolling.log: ERR_00004 The PDU buffer size is too small !. After
> encountering this error I twice raised the max PDU buffer size in server.xml
> to:
>
> maxPDUSize="40000000"
>
> And restarted the server. Unfortunately the error still occurs every now and
> then. The issue occurs seemingly randomly, independent of the accessed object
> or the LDAP client that is used. If ADS is restarted and Directory Studio
> reconnects the same object can be viewed normally.
> I'd appreciate if someone could explain why this occurs and, if possible, how
> this can be fixed. A log fragment is below. The company name as it occurs in
> the log file has been modified.
