I think we have a similar issue. I am using Glassfish v2ur1 on Solaris 10,
Sunfire T1000 for classroom use. Yesterday we were creating JDBC connection
pools to mysql databases (10 students, 10 databases on the same MySQL server).
The admin console became unresponsive and we could not move to creating JDBC
resources to these pools.

What is surprising is that only 1 of the 24 threads was busy (mpstat 1), all the
rest of the CPU threads were idle. prstat showed the Java process had a CPU
utilization of 4.4%.

I have restarted the app-server and things look ok for now, but is there a
work-around if such a thing happens again while creating JDBC resources? What is
the cause? Is there a schedule for the fix?

Thanks Manish
