• Protocol and socket errors, including exhausting available connections
• Each registered client connection, including the socket descriptor number and the protocol used.
For example:
32: Client using the ascii protocol
33: Client using the ascii protocol
Note that the socket descriptor is only valid while the client remains connected. Non-persistent
connections may not be effectively represented.
Examples of the error messages output at this level include:
<%d send buffer was %d, now %d
Can't listen for events on fd %d
Can't read from libevent pipe
Catastrophic: event fd doesn't match conn fd!
Couldn't build response
Couldn't realloc input buffer
Couldn't update event
Failed to build UDP headers
Failed to read, and not due to blocking
Too many open connections
Unexpected state %d
• Output when using
When using the second level of verbosity, you get more detailed information about protocol
operations, keys updated, chunk and network operatings and details.
During the initial start-up of
individual slab classes, the chunk sizes, and the number of entries per slab. These do not show the
allocation of the slabs, just the slabs that would be created when data is added. You are also given
information about the listen queues and buffers used to send information. A sample of the output
generated for a TCP/IP based system with the default memory and growth factors is given below:
