[sr-dev] [kamailio/kamailio] kamailio crashes when attempting to query offline database (#1821)

[srinikart]

Hello Daniel,

Thank you for your reply.   I have spent the last few weeks reviewing our system and have noticed that we have a few outdated shared libraries in use.  Unixodbc seems a bit dated as well as the odbc client SDK for the informix database engine.   I've updated the unix odbc libraries and have noticed that the segmentation fault appears to be occurring within the Informix csdk libraries.  In particular,  at a function call of SQLFreeHandle.  A few online searches has shown that there is indeed a memory violation that occurs within that function call when a protocol issue is encountered.  No further detail regarding protocol is mentioned but it seems to fit very closely to the issue at hand (TCP disconnect indicating a protocol issue and then a seg fault).  The fix to this issue is within an updated Informix CSDK library which i am in the process of installing on my system.  I am hoping this resolves the issue.  Thank you again for taking a look into this;  I will let you all know one way or another what the results are.
