Looking fine at the moment; no critical issues we are fighting.
About of tickets.
Problem with webadmin
Reported our webadmin page for tape transfers was broken --- page was hanging -- restarting httpd didn't help. Open ticket RT-8225.
Problem with pool
Problem with pool become unresponsive to admin commands. RT ticket 8227.
Problem seems to be due to large number of set-sticky messages. These are processed by the message-queue and are processed serially due to a lock in the pool's metadata. The result is that command by that are causing the message-queue threads to become blocked.
Xavier also mentioned that there was a high number of p2p server requests; due to pool being hot.

RT ticket 8229.
