This message can occur for liveCache instances only.
Tasks that run in
different threads attempt to request or release memory from the OMS heap in
parallel. This causes an increase
in the number of collisions.
Check whether the
parameter OMS_HEAP_COUNT,
which determines the number of OMS heap segments, has an optimum
value.
Generally, the risk of collision rises with the number of processors used (general database parameter MAXCPU). Check whether the liveCache instance can fulfill the requirements of the applications with fewer processors. If not, check whether the CPU on the computer is overloaded, and whether the liveCache threads are blocked by other applications running on the computer. In this case, the liveCache threads that contain user tasks should receive REAL TIME PRIORITY from the operating system. To avoid operating system blocks however, the value of MAXCPU must be at least one lower than the number of actual CPUs.
