Resolution

Follow below resolution steps

Step1: Change TCP/IP Message Buffer from 128kB to 4MB.

Linux Environments: Set the following parameters:
 
net.core.rmem_max = 4194304
net.core.wmem_max = 4194304
net.core.rmem_default = 262144
net.core.wmem_default = 262144
net.ipv4.tcp_mem = 4194304 4194304 4194304
net.ipv4.tcp_wmem = 4096 262144 4194304
net.ipv4.tcp_rmem = 4096 262144 4194304


Step2: Change the srvquery to 1 in the ini.file

Explanation:

srvquery = Determines which process responds to the agent's life sign message

You may change the setting to 1 if you experience performance issues on the PWP. Default value allocated to this parameter is 0

Values:

0: The primary work process (PWP) responds to the agent's live sign messages. (Slower)
1: The communication processes (CPs) respond to the agent's live sign messages. (Faster)
