Summary:                    [patch] Crash in app_voicemail.c in function
retrieve_file  (Read out in small chunks)
Description: 
Every few days, one of my asterisk 1.4.29 crash with this error. See
bt_full.txt
Asterisk was compiled with DONT_OPTIMIZE, so all needed information should
be visible.

there is no difference, if pooling is on with 5 or 30 as limit. Or if
pooling is disabled. The crash will happen when a higher number of blob's
are fetched parallel.

Only polling with limit 1 prevented the crash, because then, res_odbc does
only do one query at the same time.
