Symptom: RP/0/RP0/CPU0:Nov 3 14:31:25.333 : dpc_rm_svr[331]: SSE2_STATSRM: dpc_rm_svr sse2_stats_init_shmwin():41 stats shadow is not ready to use RP/0/RP0/CPU0:Nov 3 14:31:25.333 : dpc_rm_svr[331]: SSE2_STATSRM: dpc_rm_svr sse2_stats_cl_bind():324 failed to init shmwin RP/0/RP0/CPU0:Nov 3 14:31:25.333 : dpc_rm_svr[331]: SSE2_STATSRM: dpc_rm_svr sse2_stats_cl_bind():341 failed to bind, rc = 16 Nov 3 14:31:25.333 dpc_rm_svr/error 0/RP0/CPU0 t2832 Failed to bind to stats RM: 0x16 (Invalid argument) Nov 3 14:31:25.333 dpc_rm_svr/error 0/RP0/CPU0 t2832 Failed to init stats: 0x16, Invalid argument The sunstone_stats_svr process is the one which inits the stats shared mem. After the shared mem is init'd then the clients can bind. Before the stats shared mem is init'd client can't use stats. RP/0/RP0/CPU0:ott02-sim-09-uut#show process sunstone_stats_svr | i "Last started" Last started: Mon Nov 3 14:31:40 2014 But all other client which tried to bind after the sunstone_stats_svr comeup, succeed as seen below.
