Closed as program error.
Error description
There is a possibility of the RMC process losing track of an override set in "/var/ct/cfg/ctrmc.maxpktsz", and sending packets larger than the override should allow. This has been a potential exposure for several years, but has only been seen recently. For now it is suspected to simply be a rare random occurrence; this record will be updated if specific configurations or activity can make it more likely to be hit.
Local fix
Problem summary
RMC may lose track of the customer-specified packet size limit, as set in the optional configuration file "/var/ct/cfg/ctrmc.maxpktsz," resulting in RMC sending larger packets than the customer's network can handle.
Problem conclusion
The logic has been corrected to always obey the packet size configuration file.
