When Monpd is restarted, it starts printing non-stop error message to logs. Analytics statistics may be lost, and new data cannot be loaded. The ltm log contains this error signature - err stat_bridge_thread[8278]: monpd`ERR`date`11285` [stat_bridge_thread::validateCorrectNumberOfPartitions, ] Too many partitions (44) defined for DB table AVR_STAT_DISK_T


AVR statistics are lost. Monpd thread cannot load new data, and it prints non-stop error messages to the logs.


A system I/O issue (maybe caused by /var/log being full).


Run the following: find /var/avr/loader/ -mindepth 1 -name "*" -print0 | xargs -0 rm touch /var/avr/init_avrdb bigstart restart monpd
