If LTM monitor configuration parameters have custom strings that end with backslash, the saved configuration will fail to load.


The new configuration fails upon reload.


Any of the "recv", "send", or "recv-disable" parameters having a backslash at the end, and the configuration is saved.


Do not end custom strings with backslashes. If config contains monitor configuration with custom strings that end with backslash. config can be cleaned with following process: tmsh save sys ucs K42806722_before find /config/ -type f -name "bigip.conf" -exec sed -i 's/\(\(send\|recv\).*\)\\"$/\1"/g' {} + tmsh load /sys config
