Monpd allocates excessive memory on multi-blade devices, and in some cases the kernel may kill monpd. The following log signature may be encountered in /var/log/kern.log: err kernel: : [1537424.588160] Out of memory: Kill process 28371 (monpd) score 117 or sacrifice child

None.
A db variable has been added: avr.eventlogsreportrownumber, which controls the number of logs displayed. The db variable default is 10000, and supports a range from 100 through 1000000. Note: Using the maximum value may trigger the behavior described here. The system behavior depends on the specific machine hardware.
