Hi,
I am having intermittent problems w/ a java application that hangs
on a ldap read which occurs are part of the VM startup. Here is current
the env:
iplanet dir 5.1
netscape ldap sdk 4.1
java 1.3.1 03
NOTE: the hangs have occured w/ older versions
Here are the symptoms:
Based on a specific set of ldap entries, the application won't hang and
then after the addition of several entries, the application will hang.
it will hang on a different read each time. Usually it hangs on one of
several specific entries. I can query the records using a ldapsearch.
Deletion of those entries will result in the elimination of the java hang.
Does anyone have any suggestions?
The NT task list shows 11 threads. The "classic" dump shows 6 and
the new shows 9 threads. The new dump also shows: "VM Periodic Task
Thread" prio=10 tid=0x7682c0 nid=0x4dc waiting on monitor but does not
identify the monitor....
Here are the thread dumps in the "classic" format and the new format.
Thanks and please respond to [EMAIL PROTECTED]
