[SR-Users] Kamailio 1.5.4 notls Core Dump

[Stagg Shelton]

  Daniel,

Thank you for the reply back.  Unfortunately for the diagnosis with 
version 1.5.4-notls we had already upgraded to version 1.5.5-notls and 
the core files had been deleted before receiving your reply.  I can 
state that version 1.5.5-notls has not exhibited the issue that we 
experienced prior to upgrading the software.

Thank You
Stagg
