I have an Asterisk 188.8.131.52 instance that will at random intervals stop logging CDR data to MSSQL via FreeTDS.
On investigation I’ll find that the FreeTDS module has been unloaded somehow. It is not listed in cdr show status or show module like.
module load cdr_tds
module cdr_tds does not provide a license key
and the module is not loaded.
The only way to get things working again is to kill Asterisk, and do a make install again.
On restart, FreeTDS is back.
Just replacing cdr_tds.so from a backup fails, Asterisk still won’t load it.
You have to replace the asterisk binary -and- the cdr_tds.so file – their sizes change as well, and a sha256sum when FreeTDS “does not provide a license key” varies for both the main asterisk binary and the cdr_tds.so module.
I have this on multiple sites very far apart, different hardware, asterisk instances compiled at widely varying times.
Anybody encountered this before?
