Summary:                    utils.c:938 ast_carefulwrite: Timed out trying to
write causes corruption to astdb
Description: 
Agent addmember to local extensions causes the agent to be logged as
non-existent channels when ast_carefulwrite times out during login.

[Oct 15 10:40:07] NOTICE[29962]: utils.c:938 ast_carefulwrite: Timed out
trying to write
[Oct 15 10:40:07] NOTICE[29962]: utils.c:938 ast_carefulwrite: Timed out
trying to write

Here  is an example of the corruption where the same local extension is
logged twice.  The "outgoing" agent cannot logoff unless I manually remove
from astdb.  The local agent can logoff but since the outgoing cannot calls
entering queue fail to reach agents and the local channel cannot log back
in.

Local/3345 at queuefifteen-outgoing/n (dynamic) (Invalid) has taken no calls
yet
      Local/3345 at queuefifteen-agent/n (dynamic) (Not in use) has taken 2
calls (last was

This problem is easy to reproduce on an inbound call via PRI to my IVR
menu.
So I took three backtraces with gdb asterisk --pid='astersk' and I'm
uploading to this bug report.

One backtrace before seeing ast_carefulwrite appears
= threadapplyallbtpidbefore.txt

One backtrace during/between ast_carefulwrite messages
= threadapplyallbtpidduring.txt

One backtrace after ast_carefulwrite appears but before call disconnect
= threadapplyallbtpidafter..txt
