[OpenSIPS-Users] OpenSIPS libmysqlclient.so segfault after MySQL restart

[Bogdan-Andrei Iancu]

Hi Om,

Thanks for the report - I may have an idea what is the problem; I will 
try to reproduce the crash in the following days.

Could you please open a bug report on the tracker - just not to forget 
about it :D (see http://www.opensips.org/index.php?n=Development.Tracker)

Regards,
Bogdan
