Yes I am still having the behavior. I had it less in 11.3.5 than in 11.3.6. In the last 3 weeks, it has happened once each week. But I upgraded to 11.3.6 SP1 back in April. So I was somewhat surprised to have this issue so often in the last 3 weeks but was quiet prior to that. To read that ckent's entry about being at SP4, was a bit disheartening.
I am not using Derby. I am using SQL Server for AE and WCC. The database is SQL Server clustered with a replication to a DR site.
I just got a response from CA to upgrade to SP4, but I will point him to this posting to show that SP4 exhibits the problem as well.
We did issue the wcc_monitor -d % command one time and there was no change in the Quick View. We kind of panic and rebooted the two WCC servers. We are also a small show with about 4,000 jobs. So the command should not have taken too long.
