IJ07848: RMC MAY NOT OBEY CTRMC.MAXPKTSZ FILE CONTENT

APAR status

  • Closed as fixed if next.

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.  RSCT 3.2.0 is out of service on AIX except
    special product usage, so this APAR is primarily for customer
    awareness and ifix reference.
