Hi, This might not be directly Siremis-related, but in any case it is a consequence of using Siremis: The stored procedure for calculating and populating the 'cdrs' table has started to act out all of a sudden - it won't do anything. In my syslog it looks like this: May 29 09:24:01 vae /USR/SBIN/CRON[25555]: (root) CMD (echo "call kamailio_cdrs();"|/usr/bin/mysql -u root -pxxx kamailio >/dev/null) May 29 09:24:23 vae /USR/SBIN/CRON[25548]: (CRON) error (grandchild #25549 failed with exit status 1) May 29 09:24:23 vae /USR/SBIN/CRON[25548]: (CRON) info (No MTA installed, discarding output) ..and that's every time the cron job runs, the only thing that changes is the "grandchild" number. I have no clue what "grandchild" means in this context - ...anyone? Thanks!! //Anders
