Greetings Monks,
In my project Im using (running on Apache 1.3.31 + mod_perl), Im using Apache::Session::MySQL to manage logged in user sessions. On one of my boxes, I keep seeing the following message, when I do a "show processlist" on mysql: 
| 3575 | <my user> | <my ip> | <my db> | Query   | 993   | User lock  
+    | SELECT GET_LOCK('Apache-Session-6b3b6cdcc7347f1eb72f6b44df0eec3
+f', 3600)

[download]
And I notice that some of the logged in sessions have slow response time. My questions:
  1. Is this something I should worry about ?
  2. Can I do something to solve this ?
  3. Could this be the reason for slow response time ?
