The number of flows supported by a Gateway is determined by the system memory. There is a log that reflects the number of flows during startup.
The following example shows the log of maximum supported flows:
ERROR [MAIN] gwd_get_max_flow_supported:35 Flow Admission: GWD Max flow supported: 1929780 soft limit:1157820 hard limit:1736730
If logs have rolled over, use the following table as reference:
|Gateway Memory(GB)||Max Number of Flows||Critical Number of Flows(90% of max flows)|
If flow limits reach a critical limit the system should be investigated for a possible flow leak.
Current flow objects in the system are as follows:
vcadmin@vcg1-example:~$ sudo /opt/vc/bin/getcntr -c memb.mod_mp_flow_t.obj_cnt -d gwd-mem
If the flows are determined to be invalid, a diagnostic bundle should be generated before restarting the Gateway service to clear the stale flows. If the flows are determined to be valid, then the customers should be moved to alternate Gateways to reduce the flow count.
