I have created https://issues.asterisk.org/jira/browse/ASTERISK-26360 to
keep track of the
issue.  I have also put a patch up on gerrit to increase the size of the
buffer.  Since it is
unlikely that you have a Digium SLA [1] concerning certified Asterisk, the
fix will not make its
way into certified asterisk.
