lr runs 1000 concurrent operations for 20 minutes, and some errors occur during execution

Problem description

The error message is as follows: a small number of errors are reported as follows:

Error: Two Way Communication Error: Function two_way_comm_post_message / two_way_comm_post_message_ex failed.

Error: Failed to deliver a p2p message from parent to child process, reason - communication error.

Cause analysis:

Generally, there is no specific prompt information. Considering that it is a problem with the press, the concurrency is too large to handle

Solution:

Method 1: You need to modify the dat file in two locations

1. C:\Program Files (x86)\HP\LoadRunner\launch_service\dat\channel_configure.dat

2. C:\Program Files (x86)\HP\LoadRunner\dat\channel_configure.dat

Method 2: Add a press.
