APAR status

  • 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.

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.
