Good day,
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. I'd appreciate if someone could explain why this occurs and, if possible,
how this can be fixed. I added a log fragment, which is, for the sake of
readability, an attachment. The company name as it occurs in the log file has
been modified.
Best regards,
Ewald Wasscher
