Chapter 9 Troubleshooting Memory
Troubleshooting Process Memory
Examples
The show watchdog memory-state location node-id command allows you to determine the memory
state of a specified node.
RP/0/RP0/CPU0:router# show watchdog memory-state location 0/rp0/cpu0
Memory information:
Physical Memory: 4096 MB
Free Memory: 3485.671 MB
Memory State: Normal
The show process memory [job-id] location node-id command allows you to determine the processes
with the highest dynamic memory usage. The output of the command is sorted by the Dynamic memory
usage.
RP/0/RP0/CPU0:router# show processes memory location 0/rp0/cpu0
JID Text Data Stack Dynamic Process
59 65536 32768 57344 38064128 eth_server
164 147456 4096 24576 13217792 fgid_server
289 90112 4096 94208 8437760 parser_server
65554 40960 0 32768 7430144 devb-ata
Step 3
show memory job-id
Example:
RP/0/RP0/CPU0:router# show memory 123
Displays the available physical memory and memory usage
information of a specific process.
Step 4
show process memory job-id
Example:
RP/0/RP0/CPU0:router# show process memory 123
Displays information about the text, data, and stack usage
for a specific process.
Step 5
show memory compare start
Example:
RP/0/RP0/CPU0:router# show memory compare start
Takes the initial snapshot of heap memory usage for all
processes on the router and sends the report to a temporary
file named /tmp/memcmp_start.out.
Step 6
show memory compare end
Example:
RP/0/RP0/CPU0:router# show memory compare end
Takes the second snapshot of heap memory usage for all
processes on the router and sends the report to a temporary
file named /tmp/memcmp_end.out. This snapshot is
compared with the initial snapshot when displaying the
heap memory usage comparison report.
Step 7
show memory compare report
Example:
RP/0/RP0/CPU0:router# show memory compare
report s
Displays the heap memory comparison report, comparing
heap memory usage between the two snapshots of heap
memory usage.
Step 8
