Emmanuel Lecharny commented on DIRSERVER-1556:
----------------------------------------------
Is it possible that you attache the entry with the certificate that makes the
server having trouble ? (of course, not your certificate, but a faked one)
> Error message: ERR_00004 The PDU buffer size is too small !
> -----------------------------------------------------------
>
> 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-M1
>
>
> 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.
